Total revenue grew by 12.4% cc (+22.9% on a reported basis) compared to 2021, reaching record levels of EUR 6,064.0 million (EUR 5,702.7 million excluding Biotest) mainly driven by Biopharma’s key proteins following strong recovery of plasma supply. Grifols’ co-CEOs Victor Grifols Deu and Raimon Grifols Roura note: “Grifols has closed 2022 by delivering on its commitments, while taking difficult but required actions to further strengthen the organization. We want to thank the Grifols’ team for successfully navigating through a challenging year. Looking at 2023, we believe the company has a solid foundation on which to build Grifols’ future. We continue to work and innovate to provide life-saving medicines to patients, while we are committed to driving meaningful impact for all our stakeholders.” 1 Operating or constant currency (cc) excludes changes rate variations reported in the period 2 Leverage ratio consistently calculated based on the credit facilities agreement and including Biotest x Full year revenue growth of 12% cc and 23% on a reported basis driven by Biopharma’s performance (EUR 5,005 million; +20% cc; +31% reported) supported by solid underlying demand, pricing, product mix, Biotest contribution and FX tailwind x Plasma collection volumes increase by 25% vs. 2021 x Reported EBITDA improves to EUR 1,198 million, a 21.0% margin (EUR 1,221 million and 20.1% including Biotest) backed by operational leverage and cost discipline, although still impacted by high cost per liter x Net profit increases by 10.4% to EUR 208 million x Reported leverage ratio declines to 7.1x by end-year. Liquidity position at EUR 1.6bn x Grifols pursues long-term competitiveness with an operational improvement plan, which will deliver EUR 400 million annualized cash cost savings x The company provides guidance for 2023 showing revenue growth of 8-10% and significant EBITDA margin expansion.

Page 2 of 5 As Alfredo Arroyo, CFO, states, “Superior execution across our key priorities resulted in a year of transformation. We are implementing initiatives to strengthen financial performance and discipline, reflected on the announced operational improvement plan delivering EUR 400 million annualized cash cost savings. We are focused on executing to continue growing our revenue, meaningfully expanding margins and deleveraging.” Biopharma revenue reached EUR 5,005.4 million growing by 19.6% cc (+31.2% on a reported basis) compared to 2021. Underpinning this strong performance were plasma collections, robust underlying demand for key proteins and price increases. Favorable product mix was also a notable driver with subcutaneous immunoglobulin (SCIG) Xembify® sales increasing by +33.7% supported by higher demand and favorable customer mix, as well as ALBUTEIN FlexBag™ gaining traction after its launch in November 2021. Grifols Biopharma’s revenue, excluding Biotest, grew by 5.1% cc (+15.6% on a reported basis) up to EUR 4,644.1 million in 2022, reflecting a sequential acceleration with a 17.5% cc growth in the second half of the year compared to +3.3% cc in the first half of 2022. Plasma collections continued to improve, increasing by 25% in 2022 (+26% in the U.S.) compared to previous year. Growth in plasma collections in 2023 is expected to be supported by efficiencies in centers in terms of digitalization, processes and donor experience, coupled with current plasma momentum, macroeconomic backdrop and the upside from qualified Mexican national donors. Additionally, Grifols is focused on optimizing its plasma-center network by closing or consolidating underperforming centers, having closed 18 centers in the fourth quarter of 2022 and with several additional centers scheduled to be closed or consolidated in the first half of 2023. Diagnostic recorded EUR 671.3 million in revenue in 2022, down 19.7% cc (-13.8% on a reported basis) compared to 2021, primarily due to non-recurring sales of TMA (Transcription-Mediated Amplification) molecular tests, used to detect SARS-CoV-2, and the termination of mandatory Zika-virus testing, partially offset by blood typing solutions’ double-digit-growth across most geographies. Excluding the COVID-19 one-off testing and mandatory Zika-virus screening effects, the decline was 4.6% cc, impacted by pricing in NAT Donor Screening and recombinant proteins. Bio Supplies expanded by 13.2% cc (+26.1% on a reported basis) to EUR 146.1 million in 2022, following the acquisition of the remaining 51% capital of Access Biologicals, which positively impacted performance of Bio Supplies Biopharma’s cell culture media and plasma for diagnostics. Gross margin totaled 37.6% in 2022 (36.8% including Biotest) due to a double impact from Biopharma and Diagnostic. On the one hand, high cost per liter resulted from plasma collected in 2021 and the first half of 2022, due to inventory accounting (c.9-months lag). This was primarily due to elevated donor commitment compensation (DCC) and inflationary pressures on labor costs. On the other hand, COVID-19 one-off testing and Zika screening adversely impacted gross margin by 210bps in 2022 compared to previous year. Grifols is currently focused on margin expansion while achieving desired plasma volumes for 2023, reducing cost per liter to more sustainable levels. To this end, DCC’s drop by 20% in Q4 vs. its peak in July drove a 10% CPL reduction over the same reference period. Other plasma operating costs, accounting approximately for the remaining 65% of the fully-loaded plasma cost, also declined, albeit to a lesser extent, amid the current macroeconomic backdrop.

Page 3 of 5 The company recently announced operational improvement plan aims to further address these plasma-related costs through a range of measures resulting in at least EUR 300 million annualized cost savings – out of the EUR 400 million targeted for the whole Plan. EBITDA grew to EUR 1,198 million at a 21.0% margin (EUR 1,221 million and 20.1% including Biotest) in 2022, supported by operating leverage, including SG&A cost savings and R+D prioritization, partially offsetting a high cost per liter in the first half, decreased margin from Diagnostic, inflationary pressures, and high Biotest expenses, particularly related to the Biotest Next Level (BNL) project3 . Adjusted EBITDA stood at EUR 1,174 million (EUR 1,247 million including Biotest), a 20.6% margin. Excluding the impact of IFRS 164 , net financial debt totaled EUR 9,191.3 million, while the reported leverage ratio declined from 9.0x in the first half of 2022 to 7.1x for the full year 2022, following organic EBITDA improvement and enhanced inventory management. As of December 31, 2022, Grifols’ strong liquidity position totaled EUR 1,562 million, including a cash position of EUR 548 million. 2023 Guidance Testament to its commitment to enhance communication with its stakeholders, Grifols provides guidance for 2023, signaling robust total and Biopharma revenue growth of 8-10% and 10-12% cc, respectively; as well as significant margin expansion in the second half with a 23-25% EBITDA margin excluding Biotest; supported by a continued increase in plasma collections and a reduction of cost per liter and other costs, including EUR 100 million savings expected to be recognized in the profit and loss account, as part of the operational improvement plan. Including the EUR 400 million annualized cash cost savings, the EBITDA stand-alone is expected to stand at EUR 1.7 billion and 27-28% margin. Grifols’ fundamentals remain strong. The company continues to execute on its top priorities with a long-term vision, and is well-positioned for future growth, focused on business performance, operational excellence and delivering value to its stakeholders.

KPMG Auditores S.L., a limited liability Spanish company and a member firm of the KPMG global organisation of independent member firms affiliated with KPMG International Limited, a private English company limited by guarantee. All rights reserved. Paseo de la Castellana, 259C 28046 Madrid KPMG Auditores, S.L. Torre Realia Plaça d’Europa, 41-43 08908 L’Hospitalet de Llobregat (Barcelona) Independent Auditor's Report on the Consolidated Annual Accounts Reg. Mer Madrid, T. 11.961, F. 90, Sec. 8, H. M -188.007, Inscrip. 9 N.I.F. B-78510153 (Translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails.) To the Shareholders of Grifols, S.A. REPORT ON THE CONSOLIDATED ANNUAL ACCOUNTS Opinion __________________________________________________________________ We have audited the consolidated annual accounts of Grifols, S.A. (the “Parent”) and subsidiaries (together the “Group”), which comprise the consolidated balance sheet at 31 December 2022, and the consolidated income statement, consolidated statement of comprehensive income, consolidated statement of changes in equity and consolidated statement of cash flows for the year then ended, and consolidated notes. In our opinion, the accompanying consolidated annual accounts give a true and fair view, in all material respects, of the consolidated equity and consolidated financial position of the Group at 31 December 2022 and of its consolidated financial performance and its consolidated cash flows for the year then ended in accordance with International Financial Reporting Standards as adopted by the European Union (IFRS-EU) and other provisions of the financial reporting framework applicable in Spain. Basis for Opinion _________________________________________________________ We conducted our audit in accordance with prevailing legislation regulating the audit of accounts in Spain. Our responsibilities under those standards are further described in the Auditor's Responsibilities for the Audit of the Consolidated Annual Accounts section of our report. We are independent of the Group in accordance with the ethical requirements, including those regarding independence, that are relevant to our audit of the consolidated annual accounts pursuant to the legislation regulating the audit of accounts in Spain. We have not provided any non-audit services, nor have any situations or circumstances arisen which, under the aforementioned regulations, have affected the required independence such that this has been compromised. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

2 (Translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails.) Key Audit Matters ________________________________________________________ Key audit matters are those matters that, in our professional judgement, were of most significance in the audit of the consolidated annual accounts of the current period. These matters were addressed in the context of our audit of the consolidated annual accounts as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters. Assessment of the impairment testing on goodwill of the Diagnostic cash-generating unit (CGU) See notes 4 (g) and 6 to the consolidated annual accounts Key audit matter How the matter was addressed in our audit Goodwill amounts to Euros 7,011,909 thousand at 31 December 2022, of which Euros 2,773,160 thousand is from the Diagnostic cash-generating unit (CGU). The Group calculates the recoverable amount of goodwill on a yearly basis if there are indications of impairment. We identify the assessment of the impairment testing on goodwill of the Diagnostic CGU as a key audit matter, as it required significant value judgements by the Directors to evaluate the calculation of impairment, which was carried out using the discounted cash flow method. This model includes assumptions regarding future cash flows, the perpetual growth rate and discount rate, as well as the increase in sales for the Blood Typing Solutions (BTS) and Clinical Diagnostics (Cdx) lines of business. Minor changes in these assumptions could give rise to a significant effect on the Group’s measurement of the carrying amount of goodwill. The main procedures we performed to address this key audit matter were as follows: We evaluated the design and implementation and examined the operating effectiveness of certain internal controls relating to the process of assessing the impairment of goodwill, including controls related to the determination of the fair value of the Diagnostic CGU, as well as the determination of the assumptions for projected sales of the BTS and CDx lines of business, the perpetual growth rate and the discount rate. We involved our valuation specialists for the following procedures: - Evaluation of the perpetual growth rate corresponding to the Diagnostic CGU, comparing the consistency of the estimate with market data in the public domain relating to comparable entities. - Evaluation of the discount rate, comparing it with a range of discount rates calculated independently using market data in the public domain relating to comparable entities. - Analysis of the reasonableness of the discounted cash flows valuation methodology used to calculate the recoverable amount.

3 (Translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails.) Assessment of the impairment testing on the equity-accounted investment in Shanghai Raas See notes 4 (a) and 10 to the consolidated annual accounts Key audit matter How the matter was addressed in our audit Investments accounted for using the equity method amount to Euros 1,955,177 thousand at 31 December 2022, of which Euros 1,910,428 is the investment in Shanghai Raas, the shares of which are quoted on the Shenzhen stock exchange (China), for which objective evidence of impairment has been identified. At 31 December 2022 the Group has determined the recoverable amount of this investment based on its value in use, using the discounted cash flow method, the result of which has not determined the need to recognise any impairment of this investment. We identify the assessment of the equity-accounted investment in Shanghai Raas for impairment as a key audit matter, as it required significant value judgements by the Directors both in evaluating the existence of indications of impairment and in estimating the value in use, which was carried out using the discounted cash flow method. This method includes assumptions regarding the perpetual growth rate and discount rate. The main procedures we performed to address this key audit matter were as follows: We evaluated the design and implementation and examined the operating effectiveness of certain internal controls relating to the process of assessing the equity-accounted investment in Shanghai Raas for impairment, including controls related to the determination of the value in use of this investment, as well as the determination of the assumptions for the perpetual growth rate and the discount rate. We involved our valuation specialists for the following procedures: - Evaluation of the perpetual growth rate corresponding to the equity-accounted investment in Shanghai Raas, comparing it with market data in the public domain relating to comparable entities. We queried the recoverable amount calculated using a sensitivity analysis regarding the assumptions on the projection for sales of the BTS and CDx lines of business, the perpetual growth rate and the discount rate, comparing the results with the recognised amount. We evaluated the Group’s capacity to calculate the cash flow projections, comparing historical projections with actual results and the business plans approved by the Group’s governing bodies. We assessed whether the disclosures in the consolidated annual accounts meet the requirements of the financial reporting framework applicable to the Group.

Other Information: Consolidated Directors’ Report __________________________ Other information solely comprises the 2022 consolidated directors' report, the preparation of which is the responsibility of the Parent's Directors and which does not form an integral part of the consolidated annual accounts. Our audit opinion on the consolidated annual accounts does not encompass the consolidated directors' report. Our responsibility regarding the information contained in the consolidated directors’ report is defined in the legislation regulating the audit of accounts, as follows: a) Determine, solely, whether the consolidated non-financial information statement and certain information included in the Annual Corporate Governance Report and the Annual Report on Directors’ Remuneration, as specified in the Spanish Audit Law, have been provided in the manner stipulated in the applicable legislation, and if not, to report on this matter.

5 (Translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails.) b) Assess and report on the consistency of the rest of the information included in the consolidated directors’ report with the consolidated annual accounts, based on knowledge of the Group obtained during the audit of the aforementioned consolidated annual accounts. Also, assess and report on whether the content and presentation of this part of the consolidated directors’ report are in accordance with applicable legislation. If, based on the work we have performed, we conclude that there are material misstatements, we are required to report them. Based on the work carried out, as described above, we have observed that the information mentioned in section a) above has been provided in the manner stipulated in the applicable legislation, that the rest of the information contained in the consolidated directors’ report is consistent with that disclosed in the consolidated annual accounts for 2022, and that the content and presentation of the report are in accordance with applicable legislation. Directors' and Audit Committee's Responsibility for the Consolidated Annual Accounts _________________________________________________________________ The Parent's Directors are responsible for the preparation of the accompanying consolidated annual accounts in such a way that they give a true and fair view of the consolidated equity, consolidated financial position and consolidated financial performance of the Group in accordance with IFRS-EU and other provisions of the financial reporting framework applicable to the Group in Spain, and for such internal control as they determine is necessary to enable the preparation of consolidated annual accounts that are free from material misstatement, whether due to fraud or error. In preparing the consolidated annual accounts, the Parent's Directors are responsible for assessing the Group'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 Group or to cease operations, or have no realistic alternative but to do so. The Parent's audit committee is responsible for overseeing the preparation and presentation of the consolidated annual accounts. Auditor's Responsibilities for the Audit of the Consolidated Annual Accounts Our objectives are to obtain reasonable assurance about whether the consolidated annual accounts as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor'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 prevailing legislation regulating the audit of accounts 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 consolidated annual accounts.

6 (Translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails.) As part of an audit in accordance with prevailing legislation regulating the audit of accounts 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 consolidated annual accounts, 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 Group's internal control. – Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by the Parent's Directors. – Conclude on the appropriateness of the Parent's Directors' use 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 Group'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 consolidated annual accounts 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 Group to cease to continue as a going concern. – Evaluate the overall presentation, structure and content of the consolidated annual accounts, including the disclosures, and whether the consolidated annual accounts represent the underlying transactions and events in a manner that achieves a true and fair view. – Obtain sufficient appropriate audit evidence regarding the financial information of the entities or business activities within the Group to express an opinion on the consolidated annual accounts. We are responsible for the direction, supervision and performance of the Group audit. We remain solely responsible for our audit opinion. We communicate with the audit committee of the Parent 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. We also provide the Parent's audit committee with a statement that we have complied with the applicable ethical requirements, including those regarding independence, and to communicate with them all matters that may reasonably be thought to bear on our independence, and where applicable, related safeguards. From the matters communicated to the audit committee of the Parent, we determine those that were of most significance in the audit of the consolidated annual accounts of the current period and which are therefore the key audit matters.

7 (Translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails.) We describe these matters in our auditor’s report unless law or regulation precludes public disclosure about the matter. REPORT ON OTHER LEGAL AND REGULATORY REQUIREMENTS European Single Electronic Format ________________________________________ We have examined the digital files of Grifols, S.A. and its subsidiaries for 2022 in European Single Electronic Format (ESEF), which comprise the XHTML file that includes the consolidated annual accounts for the aforementioned year and the XBRL files tagged by the Company, which will form part of the annual financial report. The Directors of Grifols, S.A. are responsible for the presentation of the 2022 annual financial report in accordance with the format and mark-up requirements stipulated in Commission Delegated Regulation (EU) 2019/815 of 17 December 2018 (hereinafter the “ESEF Regulation”). In this regard, they have incorporated the Annual Corporate Governance Report and the Annual Report on Directors’ Remuneration by means of a reference thereto in the consolidated directors’ report. Our responsibility consists of examining the digital files prepared by the Directors of the Parent, in accordance with prevailing legislation regulating the audit of accounts in Spain. This legislation requires that we plan and perform our audit procedures to determine whether the content of the consolidated annual accounts included in the aforementioned digital files fully corresponds to the consolidated annual accounts we have audited, and whether the consolidated annual accounts and the aforementioned files have been formatted and marked up, in all material respects, in accordance with the requirements of the ESEF Regulation. In our opinion, the digital files examined fully correspond to the audited consolidated annual accounts, and these are presented and marked up, in all material respects, in accordance with the requirements of the ESEF Regulation. Additional Report to the Audit Committee of the Parent ____________________ The opinion expressed in this report is consistent with our additional report to the Parent's audit committee dated 27 February 2023.

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Consolidated Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) 1 (1) Nature, Principal Activities and Subsidiaries Grifols, S.A. (hereinafter the Company) was incorporated with limited liability under Spanish law on 22 June 1987. Its registered and tax offices are in Jesús i Maria, 6, 08022, 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. On 17 May 2006 the Company completed its flotation on the Spanish securities market, which was conducted through the public offering of 71,000,000 ordinary shares of Euros 0.50 par value each and a share premium of Euros 3.90 per share. The total capital increase (including the share premium) amounted to Euros 312.4 million, equivalent to a price of Euros 4.40 per share. The Company’s shares were floated on the Spanish stock exchange IBEX-35 index on 2 January 2008. All of the Company’s shares are listed on the Barcelona, Madrid, Valencia and Bilbao securities markets and on the Spanish Automated Quotation System (SIBE/Continuous Market). On 2 June 2011, Class B non-voting shares (ADRs) were listed on the NASDAQ (USA) and on the Spanish Automated Quotation System (SIBE/Continuous Market). Grifols, S.A. is the Parent of the subsidiaries listed in Appendix I of this note to the consolidated annual accounts. Grifols, S.A. and subsidiaries (hereinafter the Group) act on an integrated basis and under common management and their principal activity is the procurement, manufacture, preparation and sale of therapeutic products, especially hemoderivatives. The main factory locations of the Group’s Spanish companies are in Parets del Vallés (Barcelona) and Torres de Cotilla (Murcia), while the US companies are located in Los Angeles (California), Clayton (North Carolina), Emeryville (California), and San Diego (California). (2) Basis of Presentation The consolidated annual accounts have been prepared on the basis of the accounting records of Grifols, S.A. and of the Group companies. The consolidated annual accounts for 2022 have been prepared under International Financial Reporting Standards as adopted by the European Union (IFRS-EU) which for Grifols Group purposes, are identical to the standards as issued by the International Accounting Standard Board (IFRS-IASB) to present fairly the consolidated equity and consolidated financial position of Grifols, S.A. and subsidiaries at 31 December 2022, as well as the consolidated results from their operations, consolidated cash flows and consolidated changes in equity for the year then ended. At their meeting held on 23 February 2023 the Board of Directors of Grifols, S.A. authorized for issue the 2022 consolidated annual accounts. The consolidated annual accounts are presented in thousands of Euros, which is the functional and presentation currency of the Parent. These consolidated annual accounts for 2022 show comparative figures for 2021 and voluntarily show figures for 2020 from the consolidated statement of profit and loss, consolidated statement of comprehensive income, consolidated statement of changes in equity and consolidated statement of cash flows and their corresponding notes thereto. For the purposes of comparing the consolidated statement of profit and loss for 2022, 2021 and 2020 and the consolidated balance sheet for 2022 and 2021, the effects of the application new standards described in note 2 must be taken into account. The Group adopted IFRS-EU for the first time on 1 January 2004 and has been preparing its annual accounts under International Financial Reporting Standards, as adopted by the European Union (IFRS-EU) as required by Spanish

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Consolidated Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) 2 capital market regulations governing the presentation of financial statements by companies whose debt or own equity instruments are listed on a regulated market. In accordance with the provision of section 357 of the Irish Companies Act 2014, the Company has irrevocably guaranteed all liabilities of an Irish subsidiary undertaking, Grifols Worldwide Operations Limited (Ireland) (see Appendix I), for the financial year ended 31 December 2022 as referred to in subsection 1(b) of that Act, for the purposes of enabling Grifols Worldwide Operations Limited to claim exemption from the requirement to file their own annual accounts in Ireland. (a) Relevant accounting estimates, assumptions and judgments used when applying accounting principles The preparation of the consolidated annual accounts in conformity with IFRS-EU requires management to make judgments, estimates and assumptions that affect the application of Group accounting policies. The following notes include a summary of the relevant accounting estimates and judgments used to apply accounting policies which have the most significant effect on the amounts recognized in the consolidated annual accounts. x Determination of the fair value of assets, liabilities and contingent liabilities in relation to business combinations. The fair value methods used by the Group are detailed in note 3 x Assumptions used to test non-current assets and goodwill for impairment. Relevant cash generating units are tested annually for impairment. These are based on risk-adjusted future cash flows discounted using appropriate interest rates. The key assumptions used are specified in note 6. Assumptions relating to risk-adjusted future cash flows and discount rates are based on business forecasts and are therefore inherently subjective. Future events could cause a change in business forecasts, with a consequent adverse effect on the future results of the Group. To the extent considered a reasonably possible change in key assumptions could result in an impairment of goodwill, a sensitivity analysis has been disclosed to show the effect of changes to these assumptions and the effect of the cash generating unit (CGU) on the recoverable amount. x Evaluation of the capitalization of development costs (see note 4(d)). The key assumption is related to the estimation of sufficient future economic benefits of the projects. x The calculation of the income tax expense requires tax legislation interpretations in the jurisdictions where Grifols operates. The decision as to whether the tax authority will accept a given uncertain tax treatment and the expected outcome of outstanding litigation requires significant estimates and judgements. Likewise, Grifols recognizes deferred tax assets, mainly from tax credits and rights to deduct to the extent that it is probable that sufficient taxable income will be available against which temporary differences can be utilized, based on management assumptions regarding amount and payments of future taxable profits (see notes 4(q) and 27). x Determination of chargebacks made to certain customers in the United States (see note 4 (p)). No changes have been made to prior year judgments relating to existing uncertainties. The Group is also exposed to interest rate and currency risks. Refer to sensitivity analysis in note 29. (b) Basis of consolidation Appendix I shows details of the percentages of direct or indirect ownership of subsidiaries by the Company at 31 December 2022, 2021 and 2020, as well as the consolidation method used in each case for preparation of the accompanying consolidated annual accounts. Subsidiaries in which the Company directly or indirectly owns the majority of equity or voting rights have been fully consolidated. Associates in which the Company owns between 20% and 50% of share capital and over which it has no control but does have significant influence, have been accounted for under the equity method.

On 1 February 2021, Scranton Plasma B.V. acquired 100% of the shares of Haema Plasma Kft. Scranton is a shareholder of Grifols. On 1 February 2021 the Group signed a call option on the shares of Haema Plasma kft, exercisable by the Group only 12 months after signing and with an expiry of 48 months from the date on which the option becomes exercisable. The option price was set at thirteen times EBITDA minus net debt. The Group has potential voting rights arising from the option to purchase the shareholding and these are substantive, based on: • A call option for Grifols which gives it the irrevocable and exclusive right (not an obligation) to acquire the Haema Plasma Kft shareholding at any time after 1 February 2022. • Grifols is committed to providing support services in the business of collecting, processing and distributing plasma from the donation centres. There is also a Plasma Supply Agreement whereby the plasma produced by these entities will be used almost entirely to cover Grifols' needs. There is no sales exclusivity. • There are no shareholder agreements that provide for relevant decisions to be approved in a manner other than by majority vote. The above are indicators of the power that Grifols acquires over this entity, considering that the call option is likely to be exercised and Grifols will have the financial capacity to carry it out. Consequently, at the time the option becomes exercisable, the option empowers Grifols, even though it has not yet been exercised, and Haema Plasma Kft. is therefore included in Grifols' consolidated financial statements from 2022.

In the event of discrepancy, the Spanish-language version prevails) 18 - Grifols has a casting vote for any decision, determination and approval, with respect to the annual budget of Plasmavita and the distribution of dividends. Grifols has the power to make key business decisions. - Grifols is involved in the decision-making related to exposure or rights to variable returns from the investee. - Grifols has the casting vote to distribute dividends. Considering the above, it was concluded that Grifols has control over Plasmavita and, therefore, it is considered part of the group and it has been fully consolidated. Details of the aggregate business combination cost, the fair value of the net assets acquired and the goodwill at the acquisition date are provided below: Reference Thousands of Euros Consideration paid Cash paid 10,000 Total consideration paid 10,000 Fair value of the previous investment in the business 10,674 Fair value of net assets acquired 21,374 Non-controlling interests (10,687) Goodwill (excess of the cost of the business combination over the fair value of net assets acquired) Note 6 9,987 The amounts determined at the date of acquisition of assets, liabilities and contingent liabilities acquired are as follows: Fair Value Reference Thousands of Euros Intangible assets Note 7 177 Rights of use Note 8 7,856 Property, plant and equipment Note 9 6,506 Investment in group companies 9,548 Non-current financial assets 5,017 Inventories 1,114 Trade and other receivables 811 Other current assets 333 Cash and cash equivalents 359 Total assets 31,721 Deferred tax liabilities (1,364) Other non-current liabilites (7,575) Current liabilities (1,408) Total liabilities and contingent liabilities (10,347) Total net assets acquired 21,374 The resulting goodwill was allocated to the Biopharma segment, and it included the donor data base, licenses and workforce. If the acquisition had taken place on 1 January 2020, the net amount of the Group´s revenue and profit would not have differed significantly. The revenue and consolidated profit generated by Plasmavita between the acquisition date and 31 December 2020 are not significant for the Group.

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Consolidated Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) 19 The difference between the fair value of the previous investment and the book value amounted to Euros 5,357 thousand and has been recognized as income under “Profit/(loss) of equity accounted investees with similar activity to that of the Group” in the consolidated statement of profit and loss. The minority interest’s share of the contribution made amounts to Euros 5 million and has been recognized as a loss under the same line item. (b) Alkahest, Inc. On 2 September 2020, Grifols signed an agreement to acquire all the shares of Alkahest Inc. ("Alkahest") for a total amount of Euros 123,425 thousand (US Dollars 146,000 thousand), which was subject to approval by regulatory authorities. As part of the agreement, the Group had: x Grifols has a casting vote for any decision, determination and approval, with respect to the annual budget of Alkahest and the distribution of dividends. Grifols has the power to decide on key business decisions. x Grifols is involved in the decision-making related to exposure or rights to variable returns from the investee. Considering the above, it was concluded that Grifols has control over Alkahest and, therefore, it is considered part of the group and it has been fully consolidated. Until that date, the previous 42.45% stake in Alkahest was recorded using the equity method. The difference between the fair value of the previous investment and the book value amounted to Euros 86,743 thousand (US Dollars 102,552 thousand) and has been recognized as income under “Profit/(loss) of equity accounted investees” in the consolidated statement of profit and loss. On 15 October 2020, and as a result of the aforementioned share purchase agreement, Grifols proceeded to acquire 57.55% of the capital of Alkahest. After the transaction, the Group owns 100% of the company's share capital. Given that Grifols already had control of Alkahest, the transaction has been recorded as an agreement with the non-controlling interest, which has meant the recognition of a liability at amortized cost of Euros 121,149 thousand (US Dollars 143,706 thousand) and a decrease in "Non-controlling interests” in the amount of Euros 121,486 thousand (US Dollars 143,307 thousand), net of recorded losses and “Other reserves ”in the amount of Euros 337 thousand (US Dollars 399 thousand). At 31 December 2020, the amount payable totaled Euros 100,492 thousand and was presented under the line item “Current financial liabilities”. This amount was settled on 1 February 2021 (see note 20). Details of the aggregate business combination cost, the fair value of the net assets acquired and the goodwill at the acquisition date are provided below: Thousands of Euros Thousands of US Dollars Cost of the business combination First repurchase of non-controlling interests 18,797 22,235 Second repurchase of non-controlling interests (present value) 104,628 123,765 Total business combination cost 123,425 146,000 Fair value of the previous investment in the business 91,023 107,671 Fair value of net assets acquired 140,076 165,696 Goodwill (excess of the cost of the business combination over the fair value of net assets acquired) 74,372 87,975

The fair value of research and clinical development projects in progress that include products for neurodegenerative disorders, neuromuscular and ophthalmologic diseases have been estimated according to an income approach based on risk-adjusted discounted free cash flows. Had the acquisition taken place on 1 January 2020, the net amount of the Group´s revenue would not have changed significantly, and the net profit would have decreased by Euros 30,045 thousand. The profit of Alkahest between the acquisition date and 31 December 2020 amounted to Euros (12,317) thousand. The amount of net revenue has not changed significantly. (c) Green Cross On 20 July 2020, Grifols signed share purchase arrangements with the South Korean based GC Pharma Group and other investors for the acquisition of a plasma fractionation facility and two purification facilities located in the city of Montreal, Canada, and 11 plasma collection centers located in the United States, for a total consideration of Euros 387,917 thousand (US Dollars 457,160 thousand), on a debt free basis. On 1 October 2020, the transaction was closed. The consideration was paid with Grifols' own cash resources, and at the close of the Transaction certain equity, working capital and cash targets were guaranteed. The factories are currently in the process of obtaining the required licenses and regulatory approvals from the competent health authorities for the manufacturing of plasma-derived products. When licensed and approved, Grifols will become the only commercial manufacturer of plasma products in Canada, with a fractionation capacity of 1.5 M liters. Grifols plans to be ready to manufacture IVIG and Albumin at the factories to be able to supply the Canadian market starting in 2023.

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Consolidated Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) 21 The collection centers achieved a collection volume of 350,000 liters of plasma in 2019. Upon the execution of the Transaction, and by means of a plasma supply agreement, the Group has also committed to supplying certain output of plasma arising out of the collection centers to GC Pharma for a 24- month period. Details of the aggregate business combination cost, the fair value of the net assets acquired and the goodwill at the acquisition date are provided below: Thousands of Euros Thousands of US Dollars Consideration paid Cash paid 387,917 457,160 Total consideration paid 387,917 457,160 Fair value of net assets acquired 194,227 228,897 Goodwill (excess of the cost of the business combination over the fair value of net assets acquired) 193,690 228,263 The amounts determined at the date of acquisition of assets, liabilities and contingent liabilities are as follows: Thousands of Euros Thousands of US Dollars Other Intangible Assets 2,877 3,390 Rights of Use 11,642 13,720 Property, plant and equipement 158,148 186,377 Deferred tax assets 33,081 38,986 Other non current assets 122 144 Inventories 2,999 3,534 Trade and other receivables 3,484 4,106 Other current assets 943 1,111 Cash and cash equivalents 6,053 7,133 Total assets 219,349 258,501 Non-current financial liabilities (13,150) (15,497) Current financial liabilities (797) (939) Trade and other payables (11,175) (13,168) Total Liabilities (25,122) (29,604) Fair value of net assets acquired 194,227 228,897 Fair Value The resulting goodwill was allocated to the Bioscience segment, and it includes the donor data base, current licenses and future authorizations and workforce Had the acquisition taken place on 1 January 2020, the net amount of the Group´s revenue would have increased by Euros 31,197 thousand and the net profit would have decreased by Euros 32,423 thousand. The revenue and

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Consolidated Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) 22 profit of Green Cross between the acquisition date and 31 December 2020 amounted to Euros 4,625 thousand and Euros (5,023) thousand respectively. (4) Significant Accounting Policies (a) Consolidation Dependents Subsidiaries are considered to be those over which the Group exercises control. A subsidiary is controlled when, due to its involvement in it, it is exposed, or has the right, to variable returns and has the capacity to influence such returns through the power it exercises over it. The income, expenses and cash flows of subsidiaries are included in the consolidated financial statements from the date of acquisition, which is the date on which the Group effectively obtains control of the subsidiaries. Subsidiaries are excluded from consolidation from the date on which control is lost. Transactions and balances with Group companies and unrealized gains or losses have been eliminated in consolidation. The accounting policies of the subsidiaries have been adapted to the Group's accounting policies for transactions and other events that, being similar, have occurred in similar circumstances. The financial statements of the subsidiaries used in the consolidation process are as of the same reporting date and for the same period as those of the Parent Company. Appendix I includes information on the subsidiaries included in the Group's consolidation. Business combinations The acquisition method is used to account for the acquisition of subsidiaries in a business combination. The acquisition date is the date on which the Group obtains control of the acquired business. The acquisition cost of a subsidiary is determined at the acquisition date and comprises (i) the fair values of assets delivered, (ii) liabilities incurred or assumed, (iii) equity instruments issued, (iv) the fair value of any asset or liability resulting from a contingent consideration arrangement and (v) the fair value of any previous interest in the subsidiary. Any disbursement that is not part of the exchange for the acquired business is excluded. Acquisition-related costs are expensed as incurred. The Group recognizes identifiable assets acquired and liabilities and contingent liabilities assumed at fair value at the acquisition date. Assets held for sale, liabilities for employee compensation, transactions with payments based on equity instruments, deferred tax assets and liabilities and right-of-use assets and liabilities and lease liabilities are excluded from the application of this criterion. The excess of the consideration transferred, the amount of any non-controlling interest in the acquired subsidiary and the acquisition-date fair value of any previous interest in the acquired subsidiary over the fair value of the identifiable net assets is recorded as goodwill. If these amounts are less than the fair value of the identifiable net assets of the acquired subsidiary, the difference is recognized in profit or loss as a bargain purchase. When settlement of any part of the cash consideration is deferred, amounts payable in the future are discounted to their present value at the date of exchange. Contingent consideration is classified as equity or a financial liability. Amounts classified as a financial liability are subsequently remeasured at fair value with changes in fair value recognized in profit or loss. When the business combination could only be determined on a provisional basis, the identifiable net assets are initially recorded at their provisional values, recognizing the adjustments made during the measurement period as if they had been

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Consolidated Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) 23 known at the acquisition date, restating comparative figures for the previous year, if applicable. The adjustments to the provisional values only incorporate information relating to facts and circumstances that existed at the acquisition date and which, had they been known, would have affected the amounts recognized at that date. The measurement period should not exceed twelve months from the date of acquisition. If the business combination is carried out in stages, the acquisition-date carrying amount of the previously held equity interest of the acquiree is remeasured at its acquisition-date fair value, with any resulting gain or loss recognized in profit or loss. Non-controlling interests Non-controlling interests in subsidiaries are recorded at the acquisition date at their percentage of interest in the fair value of the identifiable net assets, without considering potential voting rights. In addition, the profit or loss for the year and each component of other comprehensive income allocated to the non-controlling interest is allocated in proportion to its percentage of ownership. Non-controlling interests in the results and equity of subsidiaries are shown separately in the consolidated statement of profit and loss, the consolidated statement of comprehensive income, the consolidated statement of changes in equity and the consolidated balance sheet, respectively. The increase and reduction of non-controlling interests in a subsidiary while maintaining control is recognized as an equity transaction in reserves. Associated Associated entities are those over which the Group exercises significant influence, understood as the capacity to intervene in financial and operating decisions, without the existence of control or joint control. Investments in associates are initially recognized at acquisition cost, including costs directly attributable to the acquisition and any active or passive contingent consideration that depends on future events or the fulfillment of certain conditions. Subsequently, investments in associates are accounted for by the equity method from the date on which significant influence is exercised until the date on which the Company can no longer justify the existence of significant influence. The excess between the cost of the investment and the Group's share of the fair values of the identifiable net assets is recorded as goodwill, which is included in the carrying amount of the investment. The shortfall, once the amounts of the cost of the investment and the identification and valuation of the net assets of the associate have been evaluated, is recorded as income in the determination of the investor's share in the results of the associate for the year in which it was acquired. The accounting policies of the associated companies have been subject to time and valuation homogenization in the same terms as those referred to in the subsidiaries. The Group's share in the profits or losses of associates obtained from the date of acquisition is recorded as an increase or decrease in the value of the investments with a credit or debit to " Profit/(loss) of equity accounted investees ". Likewise, the Group's share in the other comprehensive income of associates obtained since the acquisition date is recorded as an increase or decrease in the value of the investments in associates, with the balancing entry by nature being recognized in other comprehensive income. Dividend distributions are recorded as decreases in the value of investments. To determine the Group's share of profits or losses, including impairment losses recognized by associates, income or expenses arising from the acquisition method are considered. When the Group's share of losses on an equity accounted investment equals or exceeds its interest in the entity, the Group does not recognize additional losses unless it has incurred obligations or made payments on behalf of the other entity. The Group's share in the profits or losses of associates and changes in equity is determined on the basis of the ownership interest at year-end, without considering the possible exercise or conversion of potential voting rights. However, the Group's share is determined considering the possible exercise of potential voting rights and other derivative financial

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Consolidated Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) 24 instruments that, in substance, grant current access to the economic benefits associated with ownership interests, i.e. the right to participate in future dividends and changes in the value of associates. After applying the equity method, the Group assesses whether there is objective evidence of impairment of the net investment in the associate. The impairment calculation is determined by comparing the carrying amount of the net investment in the associate with its recoverable amount, where recoverable amount is the higher of value in use or fair value less costs of disposal. In this regard, the value in use is calculated based on the Group's share of the present value of the estimated cash flows from ordinary activities and the amounts that could result from the final disposal of the associate. The recoverable amount of the investment in an associate is assessed in relation to each associate (see note 10), unless it does not constitute a cash-generating unit (CGU). Impairment losses are not allocated to goodwill or other assets implicit in the investment in associates arising from the application of the acquisition method. In subsequent years, reversals of the value of investments are recognized against income, to the extent that there is an increase in the recoverable value. Impairment losses are presented separately from the Group's share in the results of associates. Appendix I includes information on subsidiaries and associates included in the Group's consolidation. Joint agreements Joint arrangements are those in which there is a contractual agreement to share control over an economic activity, so that decisions on the relevant activities require the unanimous consent of the Group and the other operators. Investments in joint arrangements are classified as joint operations or joint ventures, depending on the contractual rights and obligations of each investor, rather than the legal structure of the joint arrangement. Interests in joint ventures are accounted for by the equity method, after initially being recognized at cost in the consolidated balance sheet. (b) Transactions and balances in foreign currencies Transactions in foreign currencies are translated to the functional currency using the average exchange rate of the previous month provided that it does not differ significantly from the exchange rate at the date of the transaction. Foreign currency gains and losses resulting from the settlement of these transactions and from the translation of monetary assets and liabilities denominated in foreign currencies at closing exchange rates are recognized in profit or loss except when there are qualified cash flow hedges and qualified net investment hedges that are deferred to equity. The effect of exchange rate changes on cash and cash equivalents denominated in foreign currencies is presented separately in the statement of cash flows as "Effect of exchange rate changes on cash". The translation of foreign operations whose functional currency is not that of a hyperinflationary country has been made by applying the following criteria: • Assets and liabilities, including goodwill and adjustments to net assets arising from the acquisition of businesses, are translated at the closing exchange rate at each balance sheet date; • Revenues and expenses are translated at the average exchange rate of the previous month, as an approximation of the exchange rate at the date of the transaction; • Translation differences resulting from the application of the above criteria are recognized in other comprehensive income. (c) Goodwill After initial recognition, goodwill is recorded at cost, less any accumulated impairment loss, which is not reversible. Goodwill is not amortized, but is tested for impairment on an annual basis or more frequently in the event that events indicative of a potential loss in the value of the asset have been identified. For these purposes, goodwill resulting from business combinations is allocated to each of the cash generating units (CGUs) or groups of CGUs that are expected to

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Consolidated Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) 25 benefit from the synergies of the combination and the criteria referred to in note 6 are applied. CGUs or groups of CGUs are identified at the lowest level that goodwill is controlled for the purpose of internal management (Note 6). (d) Intangible assets Intangible assets are recorded at cost (acquisition or development) or at fair value when acquired in a business combination, less accumulated amortization and any accumulated impairment losses. Any expenses incurred during the research phase of projects are recognized as an expense when incurred. Costs related to development activities for internally generated intangible assets are capitalized to the extent that: • The Group has technical studies that justify the viability of the production process; • There is a commitment by the Group to complete production of the asset so that it is in a condition for sale or internal use; • The asset will generate sufficient economic benefits; • The Group has the technical and financial resources to complete the development of the asset and has developed budget control and analytical accounting systems that make it possible to monitor the budgeted costs, the modifications introduced and the costs actually charged to the various projects. These development costs are recorded as income under the heading "self-constructed non-current assets" in the consolidated statement of profit and loss when they are capitalized. Development costs previously recognized as an expense are not recognized as an asset in a subsequent period. The Group amortizes its intangible assets with finite useful lives by distributing the cost of the assets on a straight-line basis according to the following criteria: Amortisation method Rates Development expenses Straight line 10% Concessions, patents, licenses, trademarks and similar Straight line 4% - 20% Computer software Straight line 33% Currently marketed products Straight line 3% - 10% Intangible assets with indefinite useful lives are not subject to amortization but are tested for impairment at least once a year. The Group reviews the useful lives of intangible assets at the end of each year. Changes in the initially established criteria are recognized as a change in estimate. (e) Property, plant and equipment Property, plant and equipment are stated at cost, less accumulated depreciation and, if applicable, accumulated impairment losses. Cost includes, among other items, direct labor costs used in the construction of the asset and a portion of the costs indirectly attributable to the asset. These two items are recorded as income under the heading "Self-constructed non-current assets" in the consolidated statement of profit and loss, when capitalized.

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Consolidated Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) 26 Finance costs incurred that are directly attributable to the acquisition or construction of the asset until the asset is ready for use also form part of the cost. Likewise, expansion or improvement costs are included as an increase in the value of the asset when they represent an increase in its capacity or an extension of its useful life. However, maintenance costs are recognized in income when incurred. Depreciation of property, plant and equipment is provided on a straight-line basis over the estimated useful lives of the assets, less their residual value. Depreciation of property, plant and equipment is determined by applying the following criteria: Depreciation method Rates Buildings Straight line 1% - 3% Other property, technical equipment and machinery Straight line 4%-10% Other property, plant and equipment Straight line 7% - 33% The Group reviews the residual value, useful life and depreciation method of property, plant and equipment at the end of each reporting period. Changes in the initially established criteria are recognized as a change in estimate. (f) Leases Lessee The determination of whether a contract is or contains a lease is based on an analysis of the contractual arrangement and requires an assessment of whether the lessee has the right to control the use of the identified asset and to obtain all of the economic benefits from the use of the asset throughout the lease term. The lease term is the non-cancelable period considering the initial term of each contract unless the Group has a unilateral extension or termination option and there is reasonable certainty that such option will be exercised in which case the corresponding extension or early termination term will be considered. In lease contracts where the Group acts as lessee, it is recognized at the lease commencement date (i.e. the date on which the underlying asset is available for use): • A liability for the present value of the installments to be paid over the lease term, using the incremental borrowing or implicit interest rate as the discount rate when expressly indicated in the contract and, • A right-of-use asset representing the right to use the underlying leased asset during the term of the lease. Lease liabilities include fixed lease payments less any incentives, as well as variable payments that depend on an index or interest rate known at the date of inception of the lease. Also included is the exercise price of the purchase option when the lessee is reasonably certain of exercising it. After initial recognition, the liability is increased by the interest on the lease liability and reduced by the payments made. The liability is also remeasured if there are changes in the amounts payable and the lease terms. Payments included in the lease payments corresponding to maintenance, electricity, water, gas, security, cleaning, among others, are not part of the lease liability and are recognized as an expense. The incremental borrowing rate is determined taking into account: (i) geographic areas, (ii) financial term, (iii) lease term, (iv) risk-free rate as reference rate and (v) financial spread. Rights-of-use assets are measured at cost, less accumulated amortization and impairment losses (if any) and adjusted as a result of the remeasurement of the lease liability. Cost includes the amount of the initial valuation of the lease liability, as well as any amounts previously paid to the lessor prior to or at the commencement date of the lease less any incentives

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Consolidated Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) 27 received by the lessor and estimated costs to decommission the leased asset. Amortization of rights of use is provided on a straight-line basis over the shorter of the estimated useful life of the asset or the lease term. The Group applies the exception to recognition for those contracts where the lease term is 12 months or less or where the value of the leased asset (individually) when new, is less than US Dollars 5,000 or its equivalent in another currency. Consequently, in these cases, the amounts accrued will be recognized as an expense during the lease term. Lessor When the Group acts as lessor, it classifies contracts between operating and finance leases. Leases in which the Group acts as lessor while retaining a significant portion of the risks and rewards incidental to ownership of the leased asset are treated as operating leases. Otherwise, the lease is treated as a finance lease. (g) Impairment of non-financial assets Goodwill and intangible assets that have an indefinite useful life are not subject to amortization and are tested for impairment annually, or more frequently in the event of events or changes in circumstances that indicate that they may be impaired. Other assets are tested for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. When the recoverable amount is less than the carrying amount of the asset, an impairment loss is recognized in the consolidated statement of profit and loss for the difference between both amounts. The recoverable amount is the higher of an asset's fair value less costs of disposal and the estimated value in use based on discounted future cash flows expected to arise from the use of the asset. The estimate of value in use considers expectations about possible variations in the amount or timing of cash flows, the time value of money, the price to be paid for bearing the uncertainty related to the asset and other factors that affect the valuation of future cash flows related to the asset. For the purpose of assessing impairment losses, assets are grouped at the lowest levels for which there are separately identifiable cash inflows that are largely independent of the cash inflows of other assets or groups of assets (cash-generating units). Impairment losses on non-financial assets (other than goodwill) are reviewed for possible reversal at the end of each reporting period. Losses related to the impairment of CGUs are initially allocated to reduce, if applicable, the value of goodwill attributed to the CGU and then to the other assets of the CGU, pro rata based on the carrying amount of each asset, with the limit for each asset being the higher of its fair value less costs of disposal, its value in use and zero. Impairment losses related to goodwill are not reversible. (h) Financial instruments Financial assets Ranking The classification of financial assets is determined based on the characteristics of the contractual cash flows of those assets and the business model that represents how the financial assets are managed to achieve a particular business objective. In determining whether the cash flows are obtained through the receipt of contractual cash flows from the assets, consideration is given to the frequency, value and timing of sales in prior periods, the reasons for those sales and expectations regarding future sales activity. This information provides indicative data on how the Group's stated objective regarding the management of financial assets is achieved and, more specifically, how cash flows are obtained. Therefore, financial assets are classified according to the following valuation categories based on the business model and are only reclassified when, and only when their business model for managing them changes:

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Consolidated Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) 28 a) Financial assets at amortized cost: includes financial assets, including those admitted to trading on an organized market, for which the Group holds the investment under a business model whose objective is to hold financial assets to receive cash flows from the execution of the contract, and the contractual terms of the asset give rise, at specified dates, to cash flows that are solely collections of principal and interest on the principal amount outstanding. In general, the following are included in this category: i) Trade receivables: arising from the sale of goods or the rendering of services for trade transactions with deferred payment, and ii) Receivables from non-trade operations: these arise from loans or credits granted by the Group whose collections are of a determined or determinable amount. b) Financial assets at fair value through other comprehensive income: this category includes financial assets whose contractual conditions give rise, at specified dates, to cash flows that are solely collections of principal and interest on the principal amount outstanding, and are held within the framework of a business model whose objective is achieved by obtaining contractual cash flows and selling financial assets. Investments in equity instruments irrevocably designated by the Group at the time of their initial recognition are also included in this category, provided that they are not held for trading and are not to be valued at cost. c) Financial assets at fair value through profit or loss: includes financial assets held for trading and those financial assets that have not been classified in any of the above categories. Also included in this category are financial assets that are optionally designated by the Group at the time of initial recognition, which otherwise would have been included in another category, because such designation eliminates or significantly reduces a valuation inconsistency or accounting missmatch that would otherwise arise. Initial measurement Financial assets are recorded, in general terms, initially at the fair value of the consideration given plus directly attributable transaction costs. However, transaction costs directly attributable to assets recorded at fair value through profit or loss are recognized in the statement of profit and loss for the year. Trade accounts receivable are initially recognized at the amount of the consideration that is unconditional, unless they contain significant financial components, in which case they are recognized at fair value. Subsequent measurement Financial assets at amortized cost are recorded by applying this valuation criterion, charging to the statement of profit and loss the interest accrued by applying the effective interest rate method. Financial assets included in the fair value category through other comprehensive income are recorded at fair value, without deducting any transaction costs that may be incurred in their disposal. Changes in fair value are recorded directly in equity until the financial asset is derecognized or impaired, at which time the amount so recognized is taken to the statement of profit and loss. Financial assets at fair value through profit or loss are measured at fair value and the result of changes in fair value is recorded in the statement of profit and loss. Disposals of financial assets Financial assets are derecognized when the rights to receive cash flows related to them have expired or have been transferred and the Group has substantially transferred the risks and rewards of ownership.

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Consolidated Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) 29 Impairment The Group assesses, on a prospective basis, the expected credit losses associated with its debt instruments carried at amortized cost and at fair value through other comprehensive income The methodology applied for impairment depends on whether there has been a significant increase in credit risk. For trade receivables, the Group applies the simplified approach permitted by IFRS 9 which requires expected losses to be recorded from the initial recognition of the receivables, so that the Group determines expected credit losses as a probability-weighted estimate of such losses over the expected life of the financial instrument. The practical solution used is the use of a provisioning matrix based on segmentation into homogeneous asset groups, applying historical information on default rates for these groups and applying reasonable information on future economic conditions. Default rates are calculated based on current default experience over the past year, as it is a very dynamic market, and are adjusted for differences between current and historical economic conditions and considering projected information, which is reasonably available. Financial liabilities Financial liabilities assumed or incurred by the Group are classified in the following measurement categories: (a) Financial liabilities at amortized cost: are those debits and payables of the Group that have arisen from the purchase of goods and services for trading operations, or those which, without having a commercial origin, not being derivative instruments, arise from loan or credit operations received by the Group. These liabilities are initially measured at the fair value of the consideration received, adjusted for directly attributable transaction costs. Any difference between the amount received and its repayment value is recognized in the consolidated statement of profit and loss during the repayment period of the debt, applying the effective interest rate method. (b) Financial liabilities at fair value through profit or loss. Liability derivative financial instruments are measured at fair value, following the same criteria as those corresponding to financial assets at fair value through profit or loss described in the preceding section. The Group derecognizes financial liabilities when the obligations that generated them are extinguished. Assets and liabilities are presented separately in the balance sheet and are only presented at their net amount when the Group has the enforceable right to offset the recognized amounts and, in addition, intends to settle the amounts on a net basis or to realize the asset and settle the liability simultaneously. Equity instruments The Group holds financial assets, mainly equity instruments, which are measured at fair value. When Group management has opted to present gains and losses in the fair value of equity investments in other comprehensive income, after initial recognition, the equity instruments are measured at fair value, recognizing the gain or loss in other comprehensive income. Amounts recognized in other comprehensive income are not reclassified to profit or loss, but are reclassified to reserves when the instruments are derecognized. Dividends from such investments continue to be recognized in profit or loss as other income when the Group's right to receive payments is established. (i) Derivative financial instruments and hedging activities Financial derivatives are recognized at fair value at the date of the contract and at each year-end. The method for recognizing the gain or loss depends on whether the derivative is classified as a hedging instrument, and if so, the nature of the hedged asset.

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Consolidated Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) 30 For accounting purposes, they are classified as follows: (i) Derivatives qualifying for cash flow hedge accounting Hedging effectiveness Hedge effectiveness is determined at the inception of the hedging relationship, and through periodic prospective effectiveness assessments to ensure that there is an economic relationship between the hedged item and the hedging instrument. In derivatives such as the euro/dollar cross-currency swap, the Group uses the hypothetical derivative method to assess effectiveness. This hypothetical derivative is constructed without the inclusion of credit risk and currency spread. Under the hypothetical derivative method, the cumulative change in the fair value of the actual currency swap, excluding the effect of the currency spread, will be compared to the cumulative change in the fair value of the hypothetical swap. Therefore, the hypothetical derivative is constructed as a cross-currency swap with fixed euro payment, fixed U.S. dollar receipt without the inclusion of credit risk and foreign currency spread and with a fair value of zero at the date of designation. Recognition At the inception of the hedging relationship, the Group documents the economic relationship between the hedging instruments and the hedged items, including whether changes in cash flows of the hedging instruments are expected to offset changes in cash flows of the hedged items. The Group documents its risk management objective and strategy for undertaking its hedging transactions. The effective portion of changes in the fair value of derivatives designated and classified as cash flow hedges is recognized in equity under "Cash flow hedge reserve". In the case of cross-currency swaps, the currency spread of the hedging relationship is excluded and treated as hedging costs in equity. The gain or loss corresponding to the ineffective portion is recognized immediately in profit or loss for the year under the heading "Change in fair value of financial instruments". Amounts accumulated in the hedging reserve included in shareholders' equity are transferred to profit or loss when the hedged item affects profit or loss or when ineffectiveness is identified. The fair value of derivatives designated as hedges is detailed in note 29. Movements in the hedging reserve included in shareholders' equity are shown in note 16 (c). (ii) Derivatives that do not qualify for hedge accounting When derivatives do not meet the criteria for hedge accounting, they are classified as "held for trading". Changes in fair value are recognized immediately in the consolidated statement of profit and loss. (j) Own equity instruments The acquisition of treasury stock is recorded at acquisition cost, reducing equity until the time of disposal. Gains or losses on the disposal of treasury stock are recorded under "Reserves" in the consolidated balance sheet. Transaction costs related to own equity instruments, net of taxes, are recorded as a reduction of equity. (k) Inventories Inventories are stated at the lower of weighted average cost or net realizable value. Net realizable value is the estimated selling price in the normal course of business, less the estimated costs to complete production and those necessary to make the sale. For raw materials and other supplies it is the replacement cost. The cost includes direct materials, direct labor and an appropriate proportion of indirect variable and fixed costs, the latter being allocated on the basis of the normal working capacity of the means of production. The cost of plasma stocks includes the amount delivered to donors, or the amount invoiced by the seller when purchased from third parties, as well as the cost of products and devices used in the collection process, and rental and storage costs. The costs of purchased inventories

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Consolidated Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) 31 are determined after deducting discounts and rebates when it is probable that the conditions determining their concession will be met. Indirect costs such as management and administrative overheads are recognized as expenses in the period in which they are incurred. Any previously recognized inventory impairment adjustment is reversed against income under "Cost of sales" when the circumstances that caused the impairment no longer exist or when there is clear evidence of an increase in the net realizable value as a result of a change in economic circumstances. The reversal of the write-down is limited to the lower of cost and the new net realizable value of inventories. (l) Cash and cash equivalents Cash and cash equivalents include cash on hand, demand deposits with banks, other short-term highly liquid investments with an original maturity of three months or less that are readily convertible to known amounts of cash and which are subject to an insignificant risk of changes in value. (m) Government grants Government grants are recognized when there is reasonable assurance that the conditions attached to the grant will be met and that the grant will be collected. Non-refundable capital grants are recorded on the liability side of the consolidated balance sheet at the original amount granted and are recognized in the consolidated statement of profit and loss as the related assets financed are depreciated. Grants received as compensation for expenses or losses already incurred or for the purpose of providing immediate financial support not related to future expenses are credited to the consolidated statement of profit and loss. Financial liabilities that incorporate implicit aid in the form of the application of below-market interest rates are recognized initially at fair value. The difference between this value, adjusted where appropriate for the costs of issuing the financial liability and the amount received, is recorded as a government grant based on the nature of the grant. (n) Employee benefits (i) Defined contribution plans The Group records the contributions to be made to defined contribution plans as they accrue. The amount of accrued contributions is recorded under "Personnel expenses" in the consolidated statement of profit and loss in the year to which the contribution relates. (ii) Defined benefit plans The liability recognized corresponds to the present value of the obligation at the consolidated balance sheet date less the fair value of plan assets. The defined benefit obligation is calculated annually by independent actuaries using the projected unit credit method. The present value of the obligation is determined by discounting the estimated future cash flows at interest rates of bonds denominated in the currency in which the benefits will be paid and with maturities similar to those of the related obligations. Actuarial gains and losses arising from changes in actuarial assumptions or differences between assumptions and reality are recognized in equity under "Other comprehensive income". Past service costs are recognized in the consolidated statement of profit and loss under "Personnel expenses". (iii) Termination benefits Termination benefits are recognized on the earlier of the following dates: (a) when the Group can no longer withdraw the offer or (b) when the Group recognizes costs of a restructuring within the scope of IAS 37 and this results in the payment of termination benefits. (iv) Short-term employee benefits

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Consolidated Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) 32 The Group recognizes the expected cost of short-term compensation in the form of paid leave whose rights accrue as employees render the services that entitle them to receive it. If the leave is not accrued, the expense is recognized as the leave is taken. The Group recognizes the expected cost of profit sharing or employee incentive plans when there is a present legal or constructive obligation as a result of past events and a reliable estimate can be made of the value of the obligation. (v) Share-based payments The Group grants share-based payments to certain employees who are rendering services to the company. The fair value of services received is estimated by estimating the fair value of the shares granted at the grant date. Since the equity instruments granted become vested when the employees complete a certain period of service, the services received are recognized during the vesting period in the statement of profit and loss as an expense for the year with a corresponding credit to equity. The amount recognized corresponds to the amount that will be settled once the agreed conditions are met and will not be reviewed or revalued during the vesting period, as the commitment is settled in shares. If an employee resigns from his/her position before the end of the vesting period, he/she will only receive the agreed incentive in shares, being the Company's choice its settlement in cash or through equity instruments. (o) Provisions Provisions are recognized when the Group has a present legal or constructive obligation 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. Provisions are not recognized for future operating losses. The amount of the provision corresponds to the best estimate at the closing date of the disbursements required to settle the present obligation, after taking into account the risks and uncertainties related to the provision and, when significant, the financial effect of discounting, provided that the disbursements to be made in each period can be reliably determined. (p) Revenue recognition Revenue from the sale of goods or services is recognized at an amount that reflects the consideration the Group expects to be entitled to receive in exchange for transferring goods or services to a customer, at the time the customer obtains control of the goods or services rendered, i.e. when the customer has the ability to direct the use of the goods or services. The consideration committed in a contract with a customer may include fixed amounts, variable amounts, or both. The amount of consideration may vary due to discounts, rebates, incentives, performance bonuses, penalties or other similar items. Contingent consideration is only included in the transaction price when it is highly probable that the amount of revenue recognized will not be subject to significant future reversals. Revenue is presented net of value added tax and any other amounts or taxes, which in substance correspond to amounts received on behalf of third parties. (i) Sales of goods Revenue from the sale of goods is recognized when the Group satisfies the performance obligation by transferring the committed goods to the customer. An asset is transferred when the customer obtains control of that asset. In assessing the satisfaction of the performance obligation, the Group considers the following indicators of the transfer of control, which include, but are not limited to, the following: • The Group has a present right to payment for the asset. • The customer has the legal right to the asset • The Group has transferred the physical possession of the asset • Customer has the significant risks and rewards of asset ownership • The customer has accepted the asset The nature of the assets that the Group undertakes to transfer are mainly: sale of goods, sale of equipment, toll contracts, maintenance and technical service contracts, training, licenses, royalties and know-how and engineering contracts, among others.

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Consolidated Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) 33 In determining the transaction price, it is assumed that the goods and/or services are transferred in accordance with the terms of the contract. The consideration committed to a customer may include fixed amounts, variable amounts, or both. The price should be estimated taking into account the effect of variable consideration (as applicable) for returns, chargebacks/volume discounts or other incentives, provided that the same is highly probable. The Group participates in state Medicaid programs in the United States. Provision for Medicaid rebates is recorded at the time the sale is recorded in an amount equal to the estimated Medicaid rebate claims attributable to such sale. The Group determines the estimate of the accrual for Medicaid rebates primarily based on historical Medicaid rebate experience, legal interpretations of applicable laws related to the Medicaid program and any new information regarding changes in Medicaid program guidelines and regulations that could affect the amount of the rebates. The Group considers pending Medicaid claims, Medicaid payments, and inventory levels in the distribution channel and adjusts the provision periodically to reflect actual experience. Although rebate payments typically occur with a lag of one to two quarters, adjustments for actual experience have not been material. As is standard industry practice, certain customers have entered into contracts with the Group for purchases that are eligible for a price discount based on a minimum purchase quantity, volume discounts or cash discounts. These discounts are accounted for as a reduction in sales and accounts receivable in the same month in which the sales are invoiced based on a combination of the customer's actual purchase data and historical experience when the customer's actual purchase data is later known. In the United States, the Group enters into agreements with certain customers to establish contractual prices for products, which these entities purchase from the authorized wholesaler or distributor (collectively, "wholesalers") of their choice. Accordingly, when these entities purchase the products from the wholesalers at the contractual price which is lower than the price charged by the Group to the wholesaler, the Group provides the wholesaler with a credit known as a chargeback. The Group accounts for the accrual of chargebacks at the time of sale. The allowance account for chargebacks is based on the Group's estimate of the wholesaler's inventory levels and the expected direct sale of the products by the wholesalers at the contract price based on past chargeback history and other factors. The Group periodically monitors factors influencing the provision for rebates and applies adjustments when it believes that actual rebates may differ from the established allowance accounts. These adjustments occur over a relatively short period of time. As these refunds are typically settled within 30 to 45 days of sale, adjustments for actual amounts have not been material. The amount at closing for the remaining discounts is settled in the following year within 90 to 180 days depending on the type of provision. (ii) Provision of services Revenue from the rendering of services is recognized by reference to the stage of completion of the transaction at the reporting date when the outcome of the transaction can be estimated reliably. This circumstance occurs when the amount of revenue, the stage of completion, costs already incurred and costs to be incurred can be reliably measured and it is probable that the economic benefits derived from the rendering of the service will be received. In the case of services rendered for which the final result cannot be reliably estimated, revenue is recognized only up to the limit of the recognized expenses that are recoverable. (q) Income tax The income tax expense or tax credit for the year comprises both current tax and deferred tax. Current tax is the amount payable on the taxable income for the current year based on the applicable tax rate for each jurisdiction. It is calculated on the basis of the laws enacted or about to be enacted at the balance sheet date in the countries where subsidiaries and associates operate and generate taxable income. The Group periodically evaluates the positions taken in tax returns with respect to situations where the applicable tax regulations are subject to interpretation and establishes provisions, if necessary, based on the amounts expected to be paid to the tax authorities, the provision for which is included in taxable income (loss).

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Consolidated Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) 34 Deferred taxes are recognized on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the consolidated annual accounts. It is determined using tax rates (and laws) enacted or about to be enacted at the balance sheet date that are expected to apply when the related deferred tax asset is realized or the deferred tax liability is settled. Deferred taxes are not recognized if they arise from the initial recognition of an asset or liability in a transaction, other than a business combination, that at the time of the transaction affects neither accounting nor taxable income. Deferred tax assets and liabilities are also not recognized for temporary differences between the carrying amount and tax base of investments in foreign operations when the company is able to control the date on which the temporary differences will reverse and it is probable that the temporary differences will not reverse in the foreseeable future. Likewise, deferred tax liabilities are not recognized if they arise from the initial recognition of goodwill. Lastly, deferred tax assets are only recognized if it is probable that sufficient future taxable profit will be available against which they can be utilized. Deferred tax assets and liabilities are offset when there is a legally enforceable right to offset current tax assets and liabilities and when the deferred tax balances relate to the same taxation authority. Current tax assets and liabilities are offset when the entity has a legally enforceable right to offset and intends either to settle on a net basis or to realize the asset and settle the liability simultaneously. Current or deferred income tax is recognized in profit or loss, unless it arises from a transaction or economic event that has been recognized in other comprehensive income or directly in equity. In such cases, the tax is also recognized in other comprehensive income or directly in equity, respectively. The Group periodically evaluates the positions taken in tax returns with respect to situations where the applicable tax regulations are subject to interpretation and establishes provisions, if necessary, based on the amounts expected to be paid to the tax authorities, the provision for which is included in taxable income (loss). (r) Segment reporting An operating segment is a component of the Group that engages in business activities from which it may earn revenues and incur expenses, whose operating results are regularly reviewed by the Group's chief operating decision maker in order to decide on the resources to be allocated to the segment, evaluate its performance and for which discrete financial information is available. (s) Environment The Group carries out operations whose main purpose is to prevent, reduce or repair damage to the environment as a result of its activities. Items of property, plant and equipment acquired for the purpose of being used on a lasting basis in its activity and whose main purpose is the minimization of environmental impact and the protection and improvement of the environment, including the reduction or elimination of future pollution from the Group's operations, are recognized as assets through the application of measurement, presentation and disclosure criteria consistent with those mentioned in note 4(e). (5) Segment Reporting In accordance with IFRS 8 “Operating Segments”, financial information for operating segments is reported in the accompanying Appendix II, which forms an integral part of this note to the consolidated annual accounts. Group companies are divided into four areas: companies from the industrial area, companies from the commercial area, companies from the services area and companies from the research area. Within each of these areas, activities are organized based on the nature of the products and services manufactured and marketed. Assets, liabilities, income and expenses for segments include directly and reliably attributable items. Items which are not attributed to segments by the Group are: x Balance sheet: equity, cash and cash equivalents and loans and borrowings.

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Consolidated Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) 35 x Statement of profit and loss: finance result and income tax. (a) Operating segments The operating segments defined by the steering committee are as follows: x Biopharma (formerly Bioscience): concentrates all activities related to products derived from human plasma for therapeutic use. x Diagnostic: including the marketing of diagnostic testing equipment, reagents and other equipment, manufactured by Group or other companies. x Bio Supplies: this groups together transactions related to biological products for non-therapeutic use. The part relating to sales of plasma to third parties has been reclassified from Bio Supplies to Other. x Others: includes the provision of manufacturing services to third parties, plasma sales to third parties and research activities. It also includes pharmaceutical products manufactured by the Group and intended for hospital pharmacies, as well as the marketing of products that complement the Group's own products. Details of sales by groups of products for 2022, 2021 and 2020 are as follows: 31/12/2022 31/12/2021 (*) 31/12/2020 (*) Haemoderivatives 5,005,382 3,814,983 4,242,502 Transfusional medicine 640,604 712,238 714,164 Other diagnostic 21,740 23,625 27,630 146,076 115,811 133,221 Others 250,165 266,461 222,521 6,063,967 4,933,118 5,340,038 * As a consequence of the review of transactions and balances allocations by segments, the comparative figures for the fiscal year 2021 and 2020 have been adjusted accordingly. Thousands of Euros Bio supplies Total Biopharma Diagnostic At 31 December 2022, 97.6% of the income from the sale of goods and services has been recognized at a certain point-in-time (97.4% in 2021 and 97.5% in 2020). The Group has concluded that hemoderivative products are sufficiently alike to be considered as a whole for the following reasons: x All these products are human plasma derivatives and are manufactured in a similar way. x The customers and methods used to distribute these products are similar. x All these products are subject to the same regulations regarding production and the same regulatory environment. (b) Geographical information Geographical information is grouped into four areas: x United States of America and Canada x Spain x Rest of the European Union x Rest of the world

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Consolidated Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) 36 The definition of these four segments is mainly due to the geographical level that Group management sets to manage its revenue as they respond to specific economic scenarios. The main framework of the Group is consistent with this geographical segment grouping, including the monitoring of its commercial operations and its information systems. The financial information reported for geographical areas is based on sales to third parties in these markets as well as the location of assets. (c) Main customers In 2022, no customer has accounted for more than 10% of the Group's gross revenues, and nor was the case in 2021. In 2020, 10.38% of the Group's gross revenues corresponded to revenues from a customer in the Biopharma segment.

As a result of the acquisition of Talecris in 2011, and for impairment testing purposes, the Group combines the CGUs allocated to the Biopharma segment, grouping them together at segment level, because substantial synergies were expected to arise on the acquisition of Talecris, and due to the vertical integration of the business and the lack of an independent organized market for the products. Because the synergies benefit the Biopharma segment globally they cannot be allocated to individual CGUs. The Biopharma segment represents the lowest level to which goodwill is allocated and is subject to control by Group management for internal control purposes. As a result of the acquisition of Novartis’ Diagnostic business unit in 2014, the Group decided to combine Araclon, Progenika, Australia and Hologic’s share of NAT donor screening unit acquisition into a single CGU for the Diagnostic business as the acquisition is supporting not only the vertically integration business but also cross-selling opportunities. In addition, for management purposes, the Group’s management is focused on the business more than geographical areas or individual companies.

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Consolidated Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) 39 The Hospital division is no longer a reportable segment since it does not meet any of the quantitative thresholds described in IFRS 8 Operating Segments. The segment information included in the Hospital CGU in previous years is currently grouped into an Others segment. In addition, due to the acquisition of the remaining 51% stake in Access Biologicals, a new CGU for the Bio Supplies business has been identified (see note 3). The CGUs established by Grifols management are: x Biopharma x Diagnostic x Bio Supplies x Kiro Grifols x GigaGen The recoverable amount of the Biopharma CGU and Bio Supplies CGU has been calculated based on its value in use calculated as the present value of the five-year future cash flows discounted at a discount rate considering the related inherent risk. The recoverable amount of the Diagnostic CGU has been calculated based on its fair value less costs to sell calculated as the present value of future cash flows approved by Management discounted at a discount rate considering the inherent risk.. Due to the reorganization to boost the business units, a long term strategic plan has been approved in order to transform the Diagnostic business unit by investments which will lead to a beyond five year growth. Consequently, management has estimated future cash flows for the period 2023-2033. The recoverable amount of the Kiro Grifols CGU has been calculated based on its fair value less costs to sell calculated as the present value of the five-year cash flows discounted at a discount rate considering the related inherent risk. For the calculation of the recoverable amount, management has considered: x Gross margin based on historical performance and actual situation x Development prospects in the international market x Current investments x Investments which will imply a significant growth of the production capacity for those cases whose fair value has been considered Cash flows estimated as of the year in which stable growth in the CGU has been reached are extrapolated using the estimated growth rates indicated below. Perpetual growth rates are consistent with the forecasts included in industry reports. The recoverable amount of the GigaGen CGU has been determined based on the fair value less costs to sell, calculated as the present value of the future cash flows mainly of a research and development project that have been approved by management, adjusted by the probability of success and discounted at a discount rate that includes their inherent risk. Cash flows have been estimated taking into consideration a useful life of 20 years from the product launch and their reduction as of the sixth year. The key assumptions used in calculating impairment testing of the CGUs for 2021 were as follows: Perpetual Growth rate Pre-tax discount rate Bioscience 2.0% 9.0% Diagnostic 2.0% 9.3%

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Consolidated Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) 40 The key assumptions used in calculating impairment testing of the CGUs for 2022 have been as follows: Additionally, the following key assumptions have been used for the GigaGen CGU impairment testing: Likewise, for the impairment test of the Diagnostic CGU, the sales of Blood Typing Solution (BTS) and those of the Clinical Diagnostic have been considered as key assumptions. The discount rate used reflects specific risks relating to the CGUs and the countries in which they operate. The main assumptions used for determining the discount rate are as follows: • Risk free rate: normalized government bonds at 10 years • Market risk premium: premium based on market research • Unlevered beta: average market beta • Debt to equity ratio: average market ratio In 2021, the reasonably possible changes considered for the CGUs impairment testing were a variation in the discount rate, as well as in the estimated perpetual growth rate, , with independent movements of each other, as follows: In 2022, and according to the current economic context, the reasonably possible changes considered for the CGUs impairment testing are a variation in the discount rate, as well as in the estimated perpetual growth rate, with independent movements of each other, as follows: Additionally, for the impairment test of the Diagnostic CGU, two scenarios of sensitivity to variations in the sales of the Blood Typing Solutions (BTS) business line and the Clinical Diagnostics (CDx) business line have also been considered. In the first case, sales projections were estimated to be approximately 10% lower than initially projected, on average, each year. In the second case, a projection has been estimated so that Clinical Diagnostics sales from 2029 onwards represent on average 80% of the initially estimated sales.

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Consolidated Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) 48 The main movements of the equity-accounted investees with similar activity to that of the Group are explained below: Grifols Egypt for Plasma Derivatives (S.A.E.) On 29 July 2021, a cooperation agreement was signed with the National Service Projects Organization (NSPO) to help build a platform to bring self-sufficiency in plasma-derived medicines to Egypt. The Company made a first contribution of US Dollars 36,750 thousand (equivalent to Euros 30,454 thousand at the date of integration), and in exchange received GEPD shares representing 49% of its share capital, which amounts to US Dollars 300 million. The Company has undertaken to make the contributions for the outstanding amount corresponding to its interest as the capital requirements are approved. As a result, the Group made a further capital contribution of US Dollars 22 million during 2022, equivalent to 49% of the total capital contribution made (US dollars 45 million). Shanghai RAAS Blood Products Co. Ltd. In March 2019, Grifols entered into a share exchange agreement with Shanghai RAAS Blood Products Co. Ltd. (hereinafter SRAAS), through which Grifols would deliver 90 shares of its US subsidiary Grifols Diagnostic Solutions Inc. (hereinafter GDS) (representing 45% of the economic rights and 40% of the voting rights), and in exchange would receive 1,766 million of SRAAS shares (representing 26.2% of the share capital). After receiving all relevant authorizations, at 31 December 2019, Grifols delivered 90 shares of its subsidiary GDS in exchange for a contractual right to receive equity instruments in an associate (equivalent to 1,766 million of SRAAS shares), because at that date no shares of SRAAS were received. As a consequence, at 31 December 31 2019, SRAAS was the minority shareholder owning 45% of GDS. Grifols recorded the aforementioned contractual right for the fair value of the GDS shares delivered and subsequently, the right was measured based on its fair value through profit or loss. On 30 March 2020, the share exchange agreement was closed and Grifols received SRAAS shares corresponding to 26.2% of its share capital. Therefore, Grifols became the largest shareholder of SRAAS, while maintaining operational, voting and economic control of GDS. Consequently, the consolidated balance sheet at 31 December 2020, did not longer show any financial asset related to the contractual right, but the interest in SRAAS was recorded as an investment in an associate company because the Group exercises significant influence in accordance with the criteria established in IAS 28 – Investment in Associates and Joint Ventures. SRAAS’ equity-accounted investment was recognized at the value of the shares at the closing date of the transaction. The difference between the contractual right value recognized at 31 December 2019 and SRAAS quoted value at 30 March 2020 was Euros 56,526 thousand which was recognized as Change in fair value of financial instruments in the consolidated statement of profit and loss (see note 26). The impact on the consolidated statement of profit and loss related to the equity method result was included in the Operating Result under “Profit/(loss) of equity accounted investees with similar activity to that of the Group”, since SRAAS is a company dedicated to the plasma product sector. The transaction costs were recognized as part of the investment value and totaled Euros 34,088 thousand. As of 31 December 2022, the quoted value of SRAAS shares was CNY 6.34. As a result of the prolonged decline in the fair value of the associate Shanghai RAAS (hereinafter referred to as SRAAS) below its cost, there is an indication of impairment. 31/12/2022 31/12/2021 Date of acquisition SRAAS Share price CNY 6.34 CNY 6.80 CNY 7.91

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Consolidated Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) 49 The recoverable amount of the investment in SRAAS has been determined based on its value in use calculated as the present value of future cash flows discounted at a discount rate that reflects the inherent risk. Management has determined the gross margin based on past performance and the current situation, ongoing investments and its expectations of market development without considering new business. Cash flows have been estimated over 14 years since SRAAS operates in an emerging market where current investments are estimated to result in long-term growth beyond 5 years. Cash flows from the fourth year onwards are extrapolated for a further 10 years using growth rates that reduce the fourth year growth rate to the long-term growth rate shown below to better reflect medium-term growth estimates. Perpetual growth rates are consistent with forecasts included in industry and country reports. The key assumptions used to perform the impairment test of the investment in SRAAS for 2022 are as follows: Perpetual Growth rate Pre-tax discount rate SRAAS 3.3% 9.2% The discount rates used reflect the specific risks related to SRAAS and the country where it operates. The main assumptions used to determine the discount rate are as follows: x Risk-free rate: Standardized 10-year government bonds. x Market risk premium: Premium based on market studies. x Unleveraged beta: Average beta of the market. x Debt-to-equity ratio: market average ratio. In the actual economic context, the reasonably possible changes considered for SRAAS are a variation in the discount rate, as well as in the estimated perpetual growth rate, with independent movements of each other, as follows: Perpetual Growth rate Pre-tax discount rate SRAAS +/- 50 bps +/- 50 bps Reasonably possible changes in key assumptions considered by management in calculating the recoverable amount of SRAAS would cause the carrying amount to exceed its recoverable amount as follows: Pre-tax discount rate +50 bps SRAAS -2% . Plasmavita Healthcare GmbH In 2017, Grifols established PLASMAVITA GmbH, a joint venture between Grifols (50%) and two European partners (50%).

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Consolidated Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) 50 On 14 April 2020, Grifols made a contribution of Euros 10 million in cash that was recognized as a shareholder contribution in Plasmavita. The equity share of 50% remained unchanged after the contribution. However, in assessing the existence of control due to the new shareholder agreement signed on that date, it was concluded that Grifols has control over Plasmavita and, therefore, it was considered part of the group and it has been fully consolidated (see note 3). Access Biologicals LLC. On 12 January 2017, the group announced the acquisition of 49% of the voting rights in Access Biologicals LLC, a company based in San Diego, California, USA, for the amount of US Dollars 51 million. Grifols entered into an option agreement to purchase the remaining 51% voting rights in five years, in 2022. Grifols also signed a supply agreement to sell biological products not meant for therapeutic use to Access Biologicals. The principal business activity of Access Biologicals is the collection and manufacturing of an extensive portfolio of biological products. Combined with closed-loop material sourcing, it provides critical support for various markets such as in-vitro diagnostic manufacturing, biopharmaceutical, cell culture and diagnostic research & development. On 15 June 2022, Grifols, through its wholly-owned subsidiary Chiquito Acquisition Corp., reached an agreement to acquire all the shares of Access Biologicals LLC, exercising the call option for the remaining 51%, for a total of US Dollars 142 million. With the acquisition of 100% of the shares, Grifols obtains control over Access Biologicals LLC and, therefore, it is considered a group company and is consolidated under the full consolidation method (see note 3). BioDarou P.J.S. Co. On 25 April 25 2022, and after obtaining all regulatory approvals, Grifols closed the acquisition of 70.18% of the share capital of Biotest AG for Euros 1,460,853 thousand (see note 3). Biotest AG is the parent company of a consolidated group of companies, which includes a joint venture investment corresponding to a 49% interest held by Biotest Pharma GmbH in BioDarou P.J.S. Co, whose registered office is in Tehran, Iran, and which is accounted for using the equity method. The company's goal is to collect plasma, process it into immunoglobulins, factors and human albumin through Biotest AG and then sell the finished products in Iran. The main movements for the rest of the equity-accounted investees are explained below: Alkahest, Inc. On 2 September 2020, Grifols signed an agreement to acquire all the shares of Alkahest Inc. ("Alkahest") for a total amount of Euros 123,425 thousand (US Dollars 146,000 thousand), which was subject to approval by regulatory authorities. Likewise, as a result of agreements between shareholders, Grifols obtained control of Alkahest on 2 September 2020. Until that date, the previous 42.45% stake in Alkahest was equity accounted. The difference between the fair value of the previous stake and the book value was Euros 86,743 thousand (US Dollars 102,552 thousand), recognizing a profit for such amount under "Profit/(loss) of equity accounted investees" in the statement of profit and loss.

In the event of discrepancy, the Spanish-language version prevails) 54 (13) Contract assets Contract assets from contract fractionation relate to contingent claims for the complete fulfilment of contractual obligations from contract fractionation agreements entered into by Biotest AG. The resulting performance obligations are generally fulfilled by Biotest over a period of up to 12 months. Receivables from this business, which usually have a due date of between 90 and 120 days, are recognized when the right to receive the consideration becomes unconditional. This is the case when the biological drugs produced from the blood plasma provided by the customer are delivered to the customer. These are service transactions that are valued at the corresponding costs of sales incurred plus profit margin, if it can be estimated. Details of contract assets at 31 December 2022 and 2021 are as follows: 31/12/2022 31/12/2021 Contract assets (gross) 35,467 1,939 Allowances for expected credit losses (313) -- Contract assets (net) 35,154 1,939 Thousands of Euros Default risks are accounted for by making value adjustments to the contract assets. The allowance for expected credit losses is calculated as the difference between the nominal amount of the contract assets and the estimated recoverable amount. An independent expert has examined the portfolio of contract assets that do not show any concrete indications of impairment in individual cases. Movement in allowance for expected credit losses corresponding to contract assets is included in note 29.

In the event of discrepancy, the Spanish-language version prevails) 55 Other receivables During 2022, 2021 and 2020 the Grifols Group has sold receivables without recourse to some financial institutions (factors), to which the risks and benefits inherent to the ownership of the assigned credits are substantially transferred. Also, the control over the assigned credits, understood as the factor's ability to sell them to an unrelated third party, unilaterally and without restrictions, has been transferred to the factor. The main conditions of these contracts include the advanced collection of the assigned credits that vary between 70% and 100% of the nominal amount and a percentage of insolvency risk coverage on the factor side that varies between 90% and 100% of the nominal of the assigned credits. These contracts have been considered as without recourse factoring and the amount advanced by the factors has been derecognized from the balance sheet. Likewise, in financial years 2022 and 2021, some receivables assignment contracts were signed with a financial institution, in which Grifols retains the risks and benefits inherent to the ownership of the assigned credits. These contracts have been considered as with resource and the assigned amount remains in the consolidated balance sheet at 31 December 2022 and a short-term debt has been recognized for an amount equal to the consideration received from the factor for the assignment. The amount recognized is Euros 16,546 thousand at 31 December 2022 (Euros 23,450 thousand at 31 December 2021). Total receivables without recourse sold to financial institutions through the aforementioned contracts in 2022 amount to Euros 3,174,308 thousand (Euros 2,975,343 thousand in 2021 and Euros 2,735,973 thousand in 2020). The financial cost of credit rights sold for the Group totals Euros 18,201 thousand which has been recognized under finance costs in the consolidated statement of profit and loss for 2022 (Euros 10,292 thousand in 2021 and Euros 10,964 thousand in 2020) (see note 26). Details of balances with related parties are shown in note 30. The volume of invoices sold without recourse to various financial institutions which, based on their due date would not have been collected at 31 December 2022, totals Euros 445,185 thousand (Euros 317,054 thousand at December, 2021).

(a) Share capital At 31 December 2022 and 2021, the Company’s share capital amounts to Euros 119,603,705 and comprises: x Class A shares: 426,129,798 ordinary shares of Euros 0.25 par value each, subscribed and fully paid and of the same class and series. x Class B shares: 261,425,110 non-voting preference shares of 0.05 Euros par value each, of the same class and series, and with the preferential rights set forth in the Company’s by-laws. The main characteristics of the Class B shares are as follows: x Each Class B share entitles its holder to receive a minimum annual preferred dividend out of the distributable profits at the end of each year equal to Euros 0.01 per Class B share provided that the aggregate preferred dividend does not exceed the distributable profits of that year and, subject, according to the commercial law, to the approval of the distribution of dividends by the Company’s shareholders. This preferred dividend is not cumulative if sufficient distributable profits are not obtained in the period. x Each Class B share is entitled to receive, in addition to the above-mentioned preferred dividend, the same dividends and other distributions as for one Grifols ordinary share. x Each Class B share entitles the holder to its redemption under certain circumstances, if a takeover bid for all or part of the shares in the Company has been made, except if holders of Class B shares have been entitled to participate in the bid on the same terms as holders of Class A shares. The redemption terms and conditions reflected in the Company’s by-laws limit the amount that may be redeemed, requiring that sufficient distributable reserves be available, and limit the percentage of shares to be redeemed in line with the ordinary shares to which the bid is addressed. x In the event the Company were to be wound up and liquidated, each Class B share entitles the holder to receive, before any amounts are paid to holders of ordinary shares, an amount equal to the sum of (i) the par value of the Class B share, and (ii) the share premium paid for the Class B share when it was subscribed. In addition to the Class B liquidation preference amount, each holder is entitled to receive the same liquidation amount that is paid for each ordinary share. These shares are freely transferable. Since 23 July 2012 the ADSs (American Depositary Shares) representing Grifols’ Class B shares (non-voting shares) have had an exchange ratio of 1:1 in relation to Class B shares, ie.1 ADS represents 1 Class B share. The previous rate was 2 ADS per 1 Class B share. The Company’s knowledge of its shareholders is based on information provided voluntarily or in compliance with applicable legislation. According to the information available to the Company, there are no interests representing more than 10% of the Company’s total capital at 31 December 2022 and 2021. At 31 December 2022 and 2021, the number of outstanding shares is equal to the total number of Company shares, less treasury stock.

(c) Reserves The drawdown of accumulated gains is subject to legislation applicable to each of the Group companies. At 31 December 2022, Euros 18.908 thousand equivalent to the carrying amount of development costs pending amortization of certain Spanish companies (Euros 29,486 thousand at 31 December 2021) are, in accordance with applicable legislation, a distribution limitation until these development costs have been amortized. The movement in this caption of the consolidated balance sheet during the years ended at 31 December 2022, 2021 and 2020 is reflected in the consolidated statement of changes in equity, the most significant movements being detailed below: On 30 March 2020, the share exchange agreement was closed and Grifols received SRAAS shares corresponding to 26.2% of its share capital. Therefore, Grifols became the largest shareholder of SRAAS, while maintaining operational, voting and economic control of GDS (see notes 10 and 18). This transaction generated an impact of Euros 408 million on reserves. Legal reserve Companies in Spain are obliged to transfer 10% of each year‘s profits to a legal reserve until this reserve reaches an amount equal to 20% of share capital. This reserve is not distributable to shareholders and may only be used to offset losses if no other reserves are available. Under certain conditions it may be used to increase share capital provided that the balance left on the reserve is at least equal to 10% of the nominal value of the total share capital after the increase. At 31 December 2022 and 2021 the legal reserve of the Parent amounts to Euros 23,921 thousand which corresponds to 20% of the share capital. Distribution of the legal reserves of Spanish companies is subject to the same restrictions as those of the Company and at 31 December 2022 and 2021 the balance of the legal reserve of other Spanish companies amounts to Euros 2,066 thousand.

Assets of Euros 5,676 thousand were held by a trustee, company of the group, in financial year 2022 under a contractual trust arrangement (CTA) as external insolvency insurance for portions of the occupational pension scheme.

(27) Taxation Grifols, S.A. is authorized to file consolidated tax returns in Spain with Grifols Movaco, S.A., Laboratorios Grifols, S.A., Instituto Grifols, S.A., Biomat, S.A., Grifols Viajes, S.A., Grifols International, S.A., Grifols Engineering, S.A., Gripdan Invest, S.L., Araclon Biotech, Aigües Minerals de Vilajuiga, S.A. and VCN Biosciences, S.L. Grifols, S.A., in its capacity as Parent, is responsible for the filing and settlement of the consolidated tax return. Under prevailing tax law, Spanish companies pay 25% tax, which may be reduced by certain deductions. The North American company Grifols Shared Services North America, Inc. is also authorized to file consolidated tax returns in the USA with Grifols Biologicals Inc., Grifols USA, LLC., Biomat USA, Inc., Grifols Therapeutics Inc., Talecris Plasma Resources, Inc, Interstate Blood Bank, Inc. and Goetech, LLC.. The profits of the companies domiciled in the USA, determined in accordance with prevailing tax legislation, are subject to tax of approximately 22% of taxable income, which may be reduced by certain deductions. Grifols assesses the effect of uncertain tax treatments and recognizes the effect of the uncertainty on taxable earnings. At 31 of December 2022 and 2021, the potential obligations deriving from tax claims are properly covered. There are no lawsuits or uncertain tax treatments that are individually material. 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%. Under the terms in which this measure has been approved, it will have an impact on the use of tax loss carryforwards by the consolidated tax group Grifols S.A. The group is currently evaluating the impact of this measure and the alternatives that may mitigate this effect, although it is not possible to quantify this impact at this time. The Pilar 2 Law proposes to establish a worldwide minimum taxation of 15% in Corporate Income Tax (IS) for those companies with a turnover of more than 750 M€. The group is currently evaluating the impact of this measure; however it is not expected to have a significant impact on its consolidated financial statements. (a) Reconciliation of accounting and taxable income Details of the income tax expense and income tax related to profit for the year are as follows: 31/12/2022 31/12/2021 31/12/2020 Profit before income tax from continuing operations 361,257 350,453 878,629 Tax at 25% 90,313 87,613 219,657 Permanent differences (30,796) 2,503 (7,181) Effect of different tax rates 9,953 (8,720) (30,686) Tax credits (deductions) 3,667 (14,998) (14,980) Prior year income tax expense 12,685 18,908 517 Other income tax expenses/(income) 4,289 (180) 2,312 Total income tax expense 90,111 85,126 169,639 Deferred tax (15,138) 17,754 43,138 Current tax 105,249 67,372 126,501 Total income tax expense 90,111 85,126 169,639 Thousands of Euros

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Consolidated Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) 86 Movement in deferred tax assets and liabilities is as follows: Deferred tax assets and liabilities 31/12/2022 31/12/2021 31/12/2020 Balance at 1 January (481,477) (406,892) (340,803) Movements during the year 15,138 (17,754) (43,138) Business combination (note 3) (361,051) (16,400) (47,988) Translation differences (32,510) (40,431) 25,037 Balance at 31 December (859,900) (481,477) (406,892) Thousands of Euros The Spanish companies have opted to apply accelerated depreciation to certain additions to property, plant and equipment, which has resulted in the corresponding deferred tax liability. The remaining assets and liabilities recognized in 2022, 2021 and 2020 were recognized in the statement of profit and loss. Estimated net deferred tax assets to be reversed in a period of less than 12 months amount to Euros 112,274 thousand at 31 December 2022 (Euros 57,183 thousand at 31 December 2021). The majority of the tax deductions pending application from Spanish companies related mainly to research and development, mature in 18 years. Likewise, the Group estimates that practically the entire amount will be applied in five years. Tax loss carryforwards pending to be offset derived from the US companies are available for 20 years from their date of origin whilst tax losses carryforwards pending to be offset from Spanish companies registered in the Basque Country are available for 15 years and there is no maturity date for other remaining Spanish companies. The Group estimates that of the total amount of tax credits for tax losses recognized in the balance sheet at 31 December 2022 for an amount of Euros 61,152 thousand, approximately Euros 48,453 thousand will be recovered in a period of less than 5 years. The Group has not recognized as deferred tax assets the tax effect of the unused tax loss carryforwards of Group companies, which amount to Euros 121,486 thousand (Euros 123,407 thousand at 31 December 2021). The amount of unrecognized deferred tax liabilities associated with investments in subsidiaries amounted to Euros 78,947 thousand as of 31 December 2022 (Euros 52,119 thousand as of 31 December 2021). The commitments from Spanish companies from the reversal of deferred tax related to provisions of investments in subsidiaries are not significant. (c) Years open to inspection Under prevailing legislation, taxes cannot be considered to be definitively settled until the returns filed have been inspected by the taxation authorities, or the prescription period has elapsed. The main tax audits currently open in the Group are as follows: x Certain companies of the Group domiciled in Spain were subject to an inspection by the Spanish State Tax Administration Agency in relation to Corporate Income Tax for the years 2014, 2015 and 2016 and Value Added Tax for the years 2015 and 2016. As a result of said procedure, the State Tax Administration Agency issued assessments containing the results of the inspection, where it is indicated that the treatment of certain transactions and computations mainly related to Transfer Pricing should be adjusted, taking into consideration different interpretations related to the allocation of taxable bases between different jurisdictions. With respect to Corporate Income Tax, the deductibility of certain expenses for the computation of the tax payable has been questioned. These

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Consolidated Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) 87 assessments were signed in conformity by the Group on 8 November 2021. It should be noted that no penalties were imposed on any of the Group companies for any of the taxes subject to verification. The results of the inspection did not have a significant impact on the Group's consolidated annual accounts, and the differences determined by the State Tax Administration Agency were recorded as part of the current tax included under the heading "Current tax liabilities" in the Consolidated Balance Sheet as of 31 December 2021. If the result of the procedure is considered to be replicable to years not reviewed and open to inspection, the Group estimated that it was not necessary to record provisions in the consolidated annual accounts mainly because the number of transactions that gave rise to the aforementioned assessments has significantly decreased since the years in which they were inspected. Likewise, having adjusted the allocation of taxable income in accordance with the aforementioned assessments for the purposes of their consideration for the determination of Transfer Pricing, the Group now has a legal right to recover certain amounts from the corresponding Administration, in accordance with the provisions of the European Convention on International Commercial Arbitration with respect to international double taxation. The minimum amount to be recovered, upon which its realization is virtually certain, was recorded as a non-current receivable included in the caption "other payable” as of 31 December 2021. x Grifols Shared Services North America, Inc. and subsidiaries: In 2020 notification of an inspection was received relating to the State Income Tax for the fiscal years 2017 and 2018. x Certain Group companies domiciled in Spain were notified in July 2022 of the inspection by the Spanish State Tax Administration Agency in relation to Corporation Tax for the years 2017 to 2019 and Value Added Tax, personal income tax, non-resident income and capital income for the years 2018 and 2019. Group management does not expect any significant liability to derive from these inspections. Based on its experience of the different tax inspections in the different jurisdictions in which Grifols operates, the Group considers it unlikely that there will be a scenario of discrepancy with the taxation authorities that will require significant adjustments to be made to the tax result or to the asset and/or liability balances relating to corporate income tax. (28) Other Commitments with Third Parties and Other Contingent Liabilities (a) Guarantees The Group has no significant guarantees extended to third parties. (b) Guarantees committed with third parties The Group has no significant guarantees extended to third parties, except for those described in note 20. (c) Obligations with personnel The Group’s annual contribution to defined contribution pension plans of Spanish Group companies for 2022 has amounted to Euros 1,033 thousand (Euros 948 thousand for 2021). In successive years this contribution will be defined through labor negotiations. In the event that control is taken of the Company, the Group has agreements with 45 employees/directors whereby they can unilaterally rescind their employment contracts with the Company and are entitled to termination benefits ranging from two to five years’ salary.

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Consolidated Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) 88 The Group has contracts with six executives entitling them to termination benefits ranging from one to four years of their salary in different circumstances. Restricted Share Unit Retention Plan For the annual bonus, the Group established a Restricted Share Unit Retention Plan (RSU Plan), for eligible employees. Under this plan, employees can choose to receive up to 50% of their yearly bonus in non-voting Class B ordinary shares (Grifols Class B Shares) or Grifols American Depositary Shares (Grifols ADS), and the Group will match this with an additional 50% of the employee’s choice of RSUs. Grifols Class B Shares and Grifols ADS are valued at grant date. These RSU’s will have a vesting period of 2 years and 1 day and, subsequently, the RSU's will be exchanged for Grifols Class B Shares or Grifols ADS (American Depositary Share representing 1 Class B Share). If an eligible employee leaves the Company or is terminated before the vesting period, he/she will not be entitled to the additional RSU’s. At 31 December 2022, the Group has settled the RSU plan of 2019 for an amount of Euros 9,381 thousand (Euros 7,782 thousand at 31 December 2021 corresponding to the RSU plan of 2018). This commitment is treated as equity instrument and the amount totals Euros 7,304 thousand at 31 December 2022 (Euros 9,838 thousand at 31 December 2021). Savings plan and profit-sharing plan The Group has a defined contribution plan (savings plan), which qualifies as a deferred salary arrangement under Section 401 (k) of the Internal Revenue Code (IRC). Once eligible, employees may elect to contribute a portion of their salaries to the savings plan, subject to certain limitations. The Group matches 100% of the first 4% of employee contributions and 50% of the next 2%. Group and employee contributions are fully vested when contributed. The total cost of matching contributions to the savings plan was US Dollars 34.1 million in 2022 (US Dollars 31.8 million in 2021). Other plans The Group has a defined benefit pension plan for certain former Talecris Biotherapeutics, GmbH employees in Germany as required by statutory law. The pension cost relating to this plan is not material for the periods presented. (d) Purchase commitments Details of the Group’s raw material purchase commitments at 31 December 2022 are as follows: Thousands of Euros 2023 409,984 2024 413,283 2025 352,805 2026 230,625 2027 219,034 More than 5 years 281,951

GRIFOLS DIAGNOSTIC SOLUTIONS INC., GRIFOLS WORLDWIDE OPERATIONS LIMITED AND NOVARTIS VACCINES AND DIAGNOSTICS, INC. Served: 8 October 2019 US District Court, Northern District of Illinois Patent Infringement, Civil Action No. 1:19-cv-6587 Abbott Laboratories (“Abbott”), GDS, GWWO and Novartis Vaccines and Diagnostics, Inc. are in dispute over unpaid royalties payable by Abbott to GDS and Ortho-Clinical Diagnostics (“Ortho”) under an HIV License and Option agreement dated 16 August 2019 (the “HIV License”). On 12 September 2019, GDS and Ortho filed Notice of Arbitration. On 3 October 2019, Abbott terminated the HIV License and filed for Declaratory Relief seeking to invalidate the licensed patent. On March 16, 2020, Grifols and Ortho filed an answer and counterclaim to the litigation, while simultaneously pursuing arbitration for the pre-termination amount owed by Abbott. The arbitration hearing was 15-16 June 2020. Grifols/Ortho were awarded US Dollars 4 Million. NEXT ACTION: Expert Discovery was concluded on 14 October 2022, and the parties filed dispositive motions, including a motion for summary judgement by Abbott and an opposition filed by GDS, the Court has yet to rule on the motion for summary judgement filed by Abbott. GDS and Ortho contend that the patent is valid and they believe that Abbott will be unsuccessful in its Declaratory Relief action and Motion for Summary Judgment in attempting to invalidate the patent. x SIEMENS HEALTHCARE DIAGNOSTICS, INC. v. ORTHO-CLINICAL DIAGNOSTICS, INC., GRIFOLS DIAGNOSTIC SOLUTIONS INC. Served: 10 November 2020 Contract Dispute Siemens initiated dispute resolution against Ortho and GDS under the Supply Agreement alleging overpayments after an audit by Siemens. OUTCOME: Decision by the Panel issued on 27 September 2022. The Panel denied all claims by Siemens except for the cost of an audit, which resulted in a payment to Siemens in the amount of US Dollars 171,000. x RAMIREZ-VIVAR, ALFONSO v. GRIFOLS DIAGNOSTIC SOLUTIONS, INC. Served: 11 March 2021 Superior Court, CA County of Alameda Case No.: RG21089519 Wage & Hour Class Action Plaintiff claiming violation of CA wage & hour statutes.

Court recently granted class certification to a very limited portion of the class relating to only two of the ten claims alleged in the class action lawsuit. Defense counsel has reviewed the claims and provided an analysis of exposure and discuss options pertaining to defense and potential mediation. Plaintiff's counsel has requested mediation and GDS is cautiously optimistic that a settlement is possible in the coming weeks/months.

BIOMAT USA, INC., TALECRIS PLASMA RESOURCES, INC., and INTERSTATE BLOOD BANK, INC. Served: 22 June 2020 Circuit Court of Cook County Case No. 2020CH04519 Removed to Federal Court 17 July 2020, Northern District of Illinois, Case No. 20-cv-4241 Illinois Biometric Information Privacy Act Former donors allege violations of IL Biometric Information Privacy Act in a putative class action. Plaintiffs donated plasma at one of Defendants’ Illinois-based plasma donation centers. They were required to scan at least one fingerprint to donate plasma to track their identity. Plaintiffs allege that Defendants failed to comply with the BIPA’s requirements when they collected their fingerprint data. Specifically, they allege that Defendants violated the BIPA by (i) failing to develop a publicly data-retention policy and guidelines for permanently destroying biometric data, and (b) collecting, using, and storing their donors’ biometric data without obtaining informed written consent. Defendants, for their part, deny Plaintiffs’ allegations, that they have violated the BIPA, they are subject to the BIPA, or that any biometric data of donors were disclosed to any unauthorized third parties. Defendants had many defenses including the federal preemption, arguments to be made to defeat class certification, and most relevant is that Class Members signed a consent form authorizing the use of fingerprinting as biometric authentication of their identity as part of the automated screening process. NEXT ACTION: The Parties have settled this class action in the amount of $16,750,000. At the time of this settlement, discovery was beginning. The Group has properly accrued a total amount of US Dollars 6 million, and the remainder will be funded by the insurer. The Parties agreed to settle this litigation now without any admission or determination of liability or the strength of the Parties’ claims and defenses, in order to avoid further risk and expenses to Plaintiffs and the Defendants. The Parties have signed a settlement agreement and the Plaintiffs have now filed a Motion for Preliminary Approval of Class Action Settlement, and the request for a Final Approval Hearing is pending with the Court. When approved by the Court, the Parties will provide notice to the class and proceed with the settlement procedures. CLASS MEMBERS: The settlement class is 66,822 individuals. x CERUS CORPORATION v. LABORATORIOS GRIFOLS, S.A. Cerus Corporation ("Cerus") and Laboratorios Grifols, S.A. ("Grifols") entered into a Manufacturing and Supply Agreement executed in 2016, pursuant to which Grifols was to manufacture and supply to Cerus processing and filters sets to be used by Cerus in its own product (the "Agreement"). As a result of Grifols' decision to discontinue the manufacturing, sale and support of its blood bag product business worldwide, Grifols was unable to comply with the Agreement. In December 2021, Cerus filed a notice of arbitration in the UK pursuant to the terms of the Agreement alleging wrongful termination of the Agreement by Grifols. Furthermore, in January 2022, Cerus filed injunctive measures with the Courts of Rubí (Barcelona) requiring the suspension of the closure of Grifols' blood bags production facility until the arbitration proceedings is finalized. NEXT ACTION: In September the parties agreed to further suspend both the arbitration and the hearing on the injunctive measures until 28 February 2023. In the meantime, the companies are applying efforts to amicably solve technical vicissitudes in order to continue with their commercial relationship (manufacturing and supply agreement) on satisfactory terms for both parties.

The State Co. for Marketing Drugs and Medical Appliances in Iraq ("KIMADIA") awarded a tender for the supply of blood bags to Laboratorios Grifols, S.A. ("Grifols"). Grifols, through Hali/Tiba (its agent in Iraq), informed KIMADIA on Grifols' inability to supply the blood bags pursuant to the tender awarded, due to its decision to discontinue the manufacturing, sale and support of its blood bag product business. The tender documents set forth a list of penalties and compensations in case the awardee is unable to supply the products to KIMADIA. Further, Hali/Tiba also claims Grifols a compensation for the services performed in relation to the tender. NEXT ACTION: Grifols has received verbal information that KIMADIA has been able to have sourced alternative product for an agreeable pricing and that discussions among Hali/Tiba and KIMADIA have not continue on the topic of possible sanctions. However, Grifols is still waiting to obtain written confirmation on the latter or assurance that its possible claim has expired. (29) Financial Instruments (a) Classification Below is a breakdown of the financial instruments by nature, category and fair value. The Group does not provide details of the fair value of certain financial instruments as their carrying amount is very similar to their fair value because of its short term.

In the event of discrepancy, the Spanish-language version prevails) 94 (b) Measurement of fair value In order to determine the fair value of financial assets or liabilities, the Group uses the following hierarchy based on the relevance of the variables used: x Level 1: estimations based on quoted prices of the instrument. x Level 2: estimations based on significant observable variables coming directly from the market. x Level 3: estimations based on valuation techniques other than observable variables in the market, mainly discounted cash flows. (c) Financial risk management This item provides information on the Group’s exposure to risk associated with the use of financial instruments, the Group’s objectives and procedures to measure and mitigate this risk, and the Group’s capital management strategy. The Group is exposed to the following risks: x Credit risk x Liquidity risk x Market risk: includes interest rate risk, currency risk and other price risks. The Group’s risk management policies are established to identify and analyze the risks faced by the Group, define appropriate risk limits and controls and to control risks and comply with limits. Risk management policies and procedures are reviewed regularly so that they reflect changes in market conditions and the Group's activities. The Group’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. (i) Credit risk Credit risk is the risk to which the Group is exposed 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 the Group’s investments in financial assets. Trade receivables The Group does not predict any significant insolvency risks as a result of delays in receiving payment from some European countries due to their current economic situation. The main risk in these countries is that of late payments, which is mitigated through the possibility of claiming interest as foreseen by prevailing legislation. No significant bad debt or late payment issues have been detected for sales to private entities. The Group recognizes impairment based on its best estimate of the expected losses on trade and other receivables. The main impairment losses recognized are due to specific losses relating to individually identified risks. At year end, these impairment losses are immaterial. Concentration of credit risk

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Consolidated Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) 95 For trade receivables the Group uses the simplified approach, estimating lifetime expected credit losses, while for all other financial assets the Group uses the general approach for calculating expected credit losses. In both cases, due to the customers' credit rating, as well as the internal classification systems currently in place for new customers and considering that collection periods are mostly under 30 days, there is no significant impact for the Group. Exposure to credit risk The carrying amount of financial assets represents the maximum exposure to credit risk. At 31 December 2022 and 2021 the maximum level of exposure to credit risk is as follows: Carrying amount Reference 31/12/2022 31/12/2021 Non-current financial assets Nota 11 620,745 362,267 Other current financial assets Nota 11 43,663 2,029,707 Contractual assets Nota 13 35,154 1,939 Trade receivables Nota 14 608,688 432,197 Other receivables Nota 14 29,083 17,224 Cash and cash equivalents Nota 15 547,979 655,493 1,885,312 3,498,827 Thousands of Euros The maximum level of exposure to risk associated with receivables and contractual assets at 31 December 2022 and 2021, by geographical area, is as follows.

In the event of discrepancy, the Spanish-language version prevails) 97 (ii) Liquidity risk Liquidity risk is the risk that the Group cannot meet its financial obligations as they fall due. The Group’s approach to managing liquidity is to ensure where possible, that it 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. The Group 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. At 31 December 2022 the Group has total cash and cash equivalents of Euros 547,979 thousand (Euros 655,493 thousand at 31 December 2021). The Group also has approximately Euros 987,340 thousand in unused credit facilities (Euros 621,989 thousand at 31 December 2021), including Euros 937,559 thousand on the revolving credit facility (Euros 534,429 thousand at 31 December 2021). The Group is able to provide sufficient liquidity to fund its current obligations based on cash flows from operations combined with cash balances and availability of unused credit lines, and it is committed to maintaining elevated and adequate levels of liquidity through internally generated cash flows, and a decrease in dividend payments in the medium term. Additionally, currently the Group does not generate significant cash in any country that might have restrictions on the repatriation of funds. As in previous years, the Group continues with its quarterly program for optimization of working capital, which is mainly based on contracts to sell receivables without recourse. The main contractual obligations existing at the end of the fiscal year comprise mainly long-term financial debt obligations with capital repayments and interest payments (see note 20). Details of the contractual maturity dates of financial liabilities including committed interest calculated using interest rate forward curves are as follows: Carrying amount Reference Carrying amount at 31/12/22 Contractual flows 6 months or less 6 - 12 months 1-2 years 2- 5 years More than 5 years Financial liabilities Bank loans Note 20 4,041,522 5,193,051 527,770 148,914 488,105 4,028,262 -- Other financial liabilities Note 20 1,001,387 1,685,824 169,278 18,656 124,822 441,933 931,135 Bonds and other marketable securities Note 20 4,691,659 5,468,068 190,453 75,951 147,903 5,053,761 -- Lease liabilities Note 20 1,016,944 1,016,944 51,088 51,268 57,695 218,384 638,509 Payable to suppliers Note 21 731,918 731,918 731,675 243 -- -- -- Other current liabilities Note 22 14,261 14,262 11,364 2,898 -- -- -- Financial derivatives Note 29 (d) 4,736 4,736 733 -- 12 3,991 -- Total 11,502,427 14,114,803 1,682,361 297,930 818,537 9,746,331 1,569,644 Thousands of Euros

Currency risk is associated with future commercial transactions, recognized assets and liabilities, and net investments in foreign operations. The Group holds significant investments in foreign operations, the net assets of which are exposed to currency risk. The conversion risk affecting net assets of the Group’s foreign operations in US Dollars is mitigated primarily through borrowings in this foreign currency. The Group’s main exposure to currency risk is with regard to the US Dollar, which is used in a significant percentage of transactions in foreign functional currencies. The financing obtained in Euros represents 60% of the total debt of the Group and amounts to Euros 5,563 million at 31 December 2022 (69% and Euros 5,962 million at 31 December 2021). As mentioned in note 20, part of the US dollar debt of the Group is covered by a currency swap to hedge the exposure to the associated currency risk. The Group applies the cost of hedging method. This method enables the Group to exclude the currency basis spread from the designated hedging instrument and, subject to certain requirements, changes in their fair value attributable to this component are recognized in other comprehensive income. Details of the Group’s exposure to currency risk is as follows: Euros (*) US Dollars (**) Trade receivables 2,116 58,331 Receivables from Group companies 132,645 11,542 Loans to Group companies 4,548,142 33 Cash and cash equivalents 11,154 1,989 Trade payables (17,297) (20,870) Payables to Group companies (77,367) (29,277) Loans from Group companies (4,414,879) -- Bank loans (31,875) -- Balance sheet exposure 152,639 21,748 (*) Balances in Euros in subsidiaries with US Dollars functional currency (**) Balances in US Dollars in subsidiaries with Euros functional currency Thousands of Euros 31/12/2022

This analysis assumes that all other variables are held constant, especially that interest rates remain constant. A 10% weakening of the US Dollar against the Euro at 31 December 2022 and 2021 would have had the opposite effect for the amounts shown above, all other variables being held constant. The Group uses hedge accounting to partially hedge the currency risk exposure (See note 29 (d)). (iv) Interest rate risk The Group’s interest rate risks arise from current and non-current borrowings. Borrowings at variable interest rates expose the Group to cash flow interest rate risks. Fixed-rate borrowings expose the Group to fair value interest rate risk. The objective of the management of interest rate risk 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 through hedges. A significant part of the financing obtained accrues interest at fixed rates, representing 63% of the total debt of the Group at 31 December 2022 (58% at 31 December 2021). It mainly includes corporate senior notes, European Investment Bank loans, as well as the agreement with GIC (Sovereign Fund of Singapore) (see note 20). Variable-rate debt represents 37% of the total debt at 31 December 2022 (42% at 31 December 2021) and includes mainly the senior secured debt (see note 20 (b)).

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Consolidated Annual Accounts (Free translation from the original in Spanish.

As the Group does not have any hedging derivatives in place, the net effect on cash interest payments would have increased by the same amount. (v) Market price risk Price risk affecting raw materials is mitigated by the vertical integration of the hemoderivatives business in a highly concentrated sector. (d) Financial derivatives At 31 December 2022 and 2021 the Group has recognized the following derivatives: Financial derivatives Currency Notional amount at 31/12/2022 Notional amount at 31/12/2021 Value at 31/12/22 Value at 31/12/21 Maturity Cross currency interest rate swap US Dollar 500,000,000 500,000,000 35,296 5,306 15/10/2024 Cross currency interest rate swap US Dollar 205,000,000 -- 3,216 -- 15/10/2024 Foreign exchange rate forward Swiss Franc 5,500,000 -- 71 -- 28/02/2023 Foreign exchange rate forward Canadian dollar 4,416,667 -- 165 -- 2023 and 2024 Foreign exchange rate forward Pound Sterling 27,100,000 -- 805 -- 2023 Foreign exchange rate forward US Dollar 23,720,000 -- 104 -- 2023 Embedded derivative Euro 160,000,000 -- 2 -- 2024 Total assets (note 11) 39,659 5,306 Cross currency interest rate swap US Dollar 205,000,000 -- (3,990) -- 15/10/2024 Foreign exchange rate forward Canadian dollar -- 51,000,000 -- (875) 25/07/2022 Foreign exchange rate forward US Dollar 60,000,000 -- (594) -- 30/01/2023 Foreign exchange rate forward Canadian dollar 8,000,001 -- (145) -- 2024 and 2025 Foreign exchange rate forward US Dollar 15,300,000 -- (6) -- 2023 Embedded derivative Euro 65,000,000 -- (1) -- 2024 Total liabilities (note 20) (4,736) (875) Thousands of Euros

In the event of discrepancy, the Spanish-language version prevails) 101 (i) Hedging derivative financial instruments On 5 October 2021, the Group subscribed three cross currency interest-rate swaps with an aggregate value of US Dollars 500 million to hedge part of the Euro equivalent value of the US Dollar unsecured notes issued in October 2021. It is a fixed-to-fixed USD/EUR cross currency swap with the following characteristics: - The Group receives a loan of Euros 431.6 million at a nominal interest rate of 3.78%. - The Group grants a US Dollars 500 million loan at a nominal interest rate of 4.75%. On 28 June 2022, the Group subscribed one cross currency interest-rate swap of US Dollars 205 million to hedge the remaining part of the Euro equivalent value of the US Dollar unsecured notes issued in October 2021. It is a fixed-to-fixed USD/EUR cross currency swap with the following characteristics: - The Group receives a Euros 194 million loan at a nominal interest rate of 3.1046%. - The Group grants a US Dollars 205 million loan at a nominal interest rate of 4.75%. The derivative complies with the criteria required for hedge accounting. See further details in notes 4 (i). The movement in derivative financial instruments is as follows: 31/12/2022 31/12/2021 Initial balance 4,431 -- Business combination (1,255) -- Changes in fair value recognized in equity (4,757) 3,130 Transfer to profit or loss 12,552 1,895 Transfer to profit or loss - translation differences 32,954 3 Tax effect 6,170 -- Collections / Payments (15,172) (597) Ending balance 34,923 4,431 Thousands of Euros (ii) Derivative financial instruments at fair value through profit and loss The Group has subscribed various foreign exchange forwards to partially hedge the foreign currency value of intercompany loan. Since the Group chooses not to apply hedge accounting criteria, gains or losses resulting from changes in the fair value of derivatives are taken directly to “Change in fair value of financial instruments” in the consolidated statement of profit and loss. At 31 December 2022, the Group has recognized a net finance cost of Euros 2,407 thousand (Euros 280 thousand of net finance cost at 31 December 2021). (e) Capital management The directors’ policy is to maintain a solid capital base in order to ensure investor, creditor and market confidence and sustain future business development. The board of directors defines and proposes the level of dividends paid to shareholders. The capital structure is periodically reviewed through the preparation of strategic plans focused mainly on a sequential improvement of EBITDA (Earnings before interests, tax, amortization and depreciation),

(b) Conflicts of interest concerning the directors The Company’s directors and their related parties have not entered into any conflict of interest that should have been reported in accordance with article 229 of the revised Spanish Companies Act. (31) Environmental Information and Climate Change The Group carries out operations whose main purpose is to prevent, reduce or minimize the potential impact of its activities on the environment. Grifols' environmental management is based on the concept of circular economy. Priority is given to the efficient use of material resources, water and energy, and waste generation is reduced, taking into account the different stages of the life cycle of products and services. This strategy integrates the transition towards a low-carbon economy which minimizes the impact on climate change.

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Consolidated Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) 105 Grifols has a climate risk map through which it has analyzed the resilience of its strategy based on a climate scenario of a potential maximum rise of 2ºC, following the recommendations of the TCFD. The result of this analysis has enabled Grifols to assess the financial impact of the most significant risks: x Reduction in the availability of water resources: Grifols has facilities in areas where, under the simulated scenario, there could be a reduction in the availability of water resources, causing supply problems with impacts that include an increase in the price of water and production restrictions at industrial facilities. This risk can translate into increased costs associated with obtaining own water resources (well water), cleaning and proper maintenance or use of water-dependent infrastructures and industrial processes. The possible financial impact has taken into account the possibility of production stoppage and the increase in the price per m3 of water in areas with a negative price elasticity of demand. The financial impact is estimated to result in an non-relevant increase in expenditure. The results of the exposure analysis indicate that the plants that may be most exposed to this risk are those located in Barcelona and Los Angeles (USA). For each, Grifols' management of the risk varies. In Los Angeles, Grifols would have the capacity to transfer production to other plants in the group, while in Barcelona, the company has several connections to the mains water supply and also has well water extraction. Moreover, as in Los Angeles, a possible temporary stoppage of production (5 to 20 days) could be made up for by transferring production to other plants. The costs of transporting the plasma and other intermediate pastes, 50% to the Clayton plant and 50% to the Barcelona plant, would not be relevant. x New legal requirements regarding the reduction of GHG emissions: Grifols is committed to achieving carbon neutrality by 2050. Until then, new requirements could be established to reduce GHG emissions that would require greater investments for the reduction of direct emissions (Scope 1 and 2) through the installation of renewable generation technologies or changes in electricity supplies for electricity from renewable sources, among others. In the event of not being able to make such investments, Grifols expects to invest further in carbon credits to offset its carbon footprint. The projected potential financial impact to 2040 from carbon footprint reduction under current targets, would have to be assumed by the Group. The 2020-2022 Environmental Program includes the reduction of emissions through the use of 68 million kWh of renewable electricity through PPAs (Power Purchasing Agreements), the construction of two new photovoltaic plants (Barcelona and Murcia) and the construction of new refrigeration plants with refrigerant gases with a global warming potential equal to '0'. By 2022, more than 81% of the actions of this program related to climate change have already been carried out. Grifols will update this program starting in 2023 to include more ambitious reduction targets. Some of these new targets will be science-based, in accordance with the Science-based Target Initiative methodology. Exposure to this risk is expected to decrease as Grifols meets the established targets. Failing that, the answer would be to invest in carbon credits to offset the carbon footprint. x Variation in the availability of plasma resources: According to the sixth IPCC report, anthropogenic climate change would contribute to extreme precipitation, which could become more frequent in most regions due to global warming. The regions most vulnerable to these types of events which could have an impact on Grifols are the states of Texas and North Carolina, USA. The potential impact of restrictions on access to factories - with a temporary shutdown of production - and laboratories could be offset by transferring plasma to other facilities. However, plasma donation centres could suffer alterations in the plasma collection processes, as a consequence of the difficulties that donors could have in accessing them. The financial impact of reduced plasma collection in the donation centres most exposed to extreme weather events is estimatednot to be relevant.

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Consolidated Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) 106 The results of the exposure analysis indicate that plasma centres may be the most exposed to this risk. However, the fact that they are widely spread over several regions allows dilution of any potential impact. The analysis was conducted taking into account the centres most exposed to an increase in the severity of weather events such as hurricanes and tropical storms. In the worst-case scenario of centre closures, production would not be substantially affected, so the impact would be limited to the temporary unavailability of plasma in the directly affected centres, resulting in reduced availability of plasma drugs. x Transition to low-emission technologies: In the geographical areas in which Grifols operates, meeting the 2030 decarbonization targets is based on the principles of technological neutrality and cost-efficiency, requiring high investments in innovation and infrastructure. Of particular note are the major investments associated with the installation of air conditioning, boiler and renewable energy generation technologies aimed at reducing Grifols' emissions and increasing energy efficiency. The technologies present in the production plants which contribute most to the carbon footprint are boilers, which use fossil fuels in their operation, and their potential impact is their replacement with low-emission options. With the aim of replacing the most polluting technologies, Grifols regularly analyses the technological options available on the market, with a special focus on technologies that increase its climate resilience. Currently, there is no consensus on a single technology that can generate the heat needed on an industrial scale without using fossil fuels. Grifols is aware that renewable hydrogen could be a valuable energy vector for end uses, being an alternative for obtaining good yields at a reasonable cost. At present, the use of renewable hydrogen is in its infancy, although Grifols is monitoring its development in order to study its viability in the near future. In the simulated scenario, Grifols recognizes that in order to manage this risk in its entirety, the replacement of boilers must be carried out progressively and will depend on the progress and availability of these technologies on the market. It also takes into account heat generation processes using electrical technologies such as thermocompression. The investment in environmental assets during the year ended 31 December 2022 is Euros 8,372 thousand (Euros 7,363 thousand in the year ended 31 December 2021 and Euros 2,751 thousand in the year ended 31 December 2020), mainly intended to optimize water consumption, improvements in wastewater treatment, eco-efficiency projects in the use of energy and the replacement of refrigerant gases with others with a lower environmental impact. The expenses incurred by the Group for the protection and improvement of the environment in 2022 amounted to approximately Euros 25,787 thousand (Euros 20,642 thousand in 2021 and Euros 20,495 thousand in 2020). With the procedures currently in place, the Group considers that environmental risks are adequately controlled. The Group's strategy is aligned with the objectives of the Paris Agreement, and has been considered in the evaluation of the useful lives of assets and in the impairment analysis of non-financial assets. The Group does not anticipate impairment of assets before the established amortization periods. The Group has not received any environmental subsidies during fiscal years 2022, 2021 and 2020.

New opportunities. Almost four decades ago, I followed in my father’s footsteps and took up the helm of what was, at that time, a family business, embarking upon a journey that would see me spearhead and witness one of the great transformations of Grifols. It was back in the 80s, and flanked by a loyal, highly motivated team, we started to expand our production capacity, seek out new business opportunities and take the company global. In 2006 we took the company public to compete on a level playing field with the big industry names, and in 2011 the acquisition of Talecris positioned us as one of the indisputable sector leaders. It was a time of sacrifice, just as this present time is. A time of strategic decision-making, just as this year has been. And above all, it was a time to prioritize what was best for Grifols, as always. Because one thing we know for sure is that what is best for Grifols is what is best for thousands of patients, donors and healthcare professionals. It is what is best for our people, our shareholders, and society. We have been safeguarding people’s health and well-being for 115 years and we will continue to do so, with the utmost responsibility and great optimism. In October 2022 I decided to step down from my role as Chairman of the Board of Directors of Grifols, though I shall stay on as Chairman of Honour, The Executive Chairman, the current CEOs and rest of the management make a formidable team; one which is fully equipped to take Grifols into the future and, as it has already demonstrated, to reverse the situation triggered by COVID-19, a global pandemic with a severe long-term impact. This is not the first storm we have weathered. There have been plenty of times in Grifols’ history when we have had to give it our all and work harder and better to build a stronger company. The transformation is underway, and we have taken all the necessary measures to remain positioned as a top global player which is fully committed to improving the health and well-being of people all over the world. Now, with the integration of Biotest, our new strategic plans and our enhanced capacity to deliver, I can assure you that at Grifols, the best is yet to come. VÍCTOR GRÍFOLS ROURA CHAIRMAN OF HONOUR OF GRIFOLS “What is best for Grifols is what is best for thousands of patients, donors and healthcare professionals. It is what is best for our people, our shareholders, and society. As Chairman of Honour, I will make sure this never changes”

2022 Consolidated Directors’ Report · 6 “Grifols has robust fundamentals and a clear roadmap to build an even stronger position going forward. Growth, sustainability and a long-term approach are the hallmarks of our business” VÍCTOR GRÍFOLS DEU, CO-CEO Transformational spirit For Grifols, 2022 brought a burgeoning recovery and an improving operating and financial performance, even against a macroeconomic backdrop of inflation, uncertainty and volatile financial markets. The decisions made in previous years to enhance our plasma supply capacity drove a consistent increase in donations, particularly in the US market, with donations up 25% over the year to stand at record 2019 levels. Over the course of the year we have implemented operational improvement plans and an internal reorganization based on more independent business units – Plasma Procurement, Biopharma, Diagnostic and Bio Supplies – with a view to improving our competitive position. We took a close look this year at all of our business areas and functions to see where we can deliver better organizational efficiency and become more responsive and proactive. Sadly, these changes will give rise to an 8% reduction in our workforce, which will largely impact our US Plasma Procurement unit. We also undertook a comprehensive review of our innovation projects to ensure we are channeling our efforts into the most viable, high-potential ideas, as well as designing a new structure to drive faster progress on these projects. This allowed us to successfully optimize our R&D pipeline and investments as well as delivering an improvement in terms of risk-opportunity profile. In April, we completed the acquisition of Biotest AG. This major milestone will allow us to increase the availability of plasma-derived therapies, expand our product portfolio to better respond to patients’ needs, step up our innovation strategy and grow our global footprint. It has also allowed us to create Europe’s largest private network of plasma donation centers. The outstanding results reported in 2022 clearly evidence the effort we have all put in to generating growth and improving our operational performance. We want to extend our thanks to every member of the Grifols team for their hard work and constant dedication. Without their commitment, we could never have forged a new strategic partnership with Canadian Blood Services, secured FDA clearance for the AlphaID™ At Home Genetic Health Risk Service, opened a new albumin filling plant in Ireland or launched our subcutaneous immunoglobulin treatment Xembify in Europe, to name but a few of this year’s achievements.

2022 Consolidated Directors’ Report · 7 “Our 2022 results are a clear reflection of the effort and hard work put in by every member of the Grifols team in recent years. Donors, patients and our team are our constant priority” RAIMON GRIFOLS ROURA, CO-CEO In addition to these transformational measures, it is important to highlight that Grifols’ business activity is geared towards improving patients’ lives and contributing decisively to sustainability, because in our view, a project which is sustainable and profitable over the long term must also be ethically, socially and environmentally responsible. We are determined to reinforce our position as one of the world’s most sustainable companies. In 2022, Grifols was included for the third year running in the Dow Jones Sustainability Index (DJSI), the world’s leading sustainability benchmark. We also made significant inroads in deploying our ESG strategy, which is underpinned by the six core pillars and 30 specific goals comprising the Grifols 2030 Agenda. We are proud of the progress made, while we continued support for the UN Global Compact and its ten principles. We responded successfully to other challenges this year, too. We increased training hours to nearly 220 hours per employee, secured progress in equality, diversity and inclusion, and delivered an overall improvement in our gender pay gap. We took environmental action, paring down our greenhouse gas emissions and working on using natural resources more efficiently, as well as moving ever closer to our target of using energy from renewable sources only by 2030. We also continue to roll out ambitious, far-reaching social investment initiatives with donors, patients and patients’ associations, as well as supporting the endeavors of our three foundations. This year 2022 brought great change, but thanks to our transformational spirit, sustainable leadership and responsible growth, we forged ahead with integrity, rigor and an unwavering commitment to the values and ethical principles that have guided us for 115 years. Thank you for believing in us.

This ambition is reflected in Grifols’ Sustainability Policy and 2021-23 Sustainability Master Plan, incorporated in its Strategic Plan and aligned with the United Nations Sustainable Development Goals (SDGs). Based on an in-depth analysis of the company’s relevant or material aspects, the Sustainability Master Plan outlines the 30 corporate objectives that form Grifols 2030 Agenda. Overview of Grifols’ relevant aspects In 2022, Grifols identified its relevant aspects based on their current or potential impact in the short, medium and long term (impact materiality), as well as those that might generate financial risks or opportunities and therefore affect the company’s value in the short, medium and long term (financial materiality). This double analysis (double materiality) led to an objective and strategic matrix, allowing Grifols to update its ESG sheet. IMPACT MATERIALITY FINANCIAL MATERIALITY 5 4 3 2 1 12345 1. Minimum 2.

Grifols will produce immunoglobulins exclusively for CBS at its new fractionation plant in Montreal. This is the first time CBS has signed this type of agreement. Based on Grifols’ leadership in establishing private-public-sector partnerships, this is the best way to ensure countries’ plasma self-sufficiency. Canada has high Ig consumption, currently importing up to 85% of this plasma protein. To help address the country’s needs, Grifols is creating a vertical supply chain with new plasma donation centers to be opened in the coming years and already-acquired production facilities, including its manufacturing plant in Montreal and a plasma donation center in Winnipeg. The manufacturing process will take place in Grifols’ Clayton (North Carolina) plant until the Montreal plant is fully operational in 2026. Egypt, pioneering in the Middle East and Africa Grifols signed a strategic alliance with the Egyptian government in 2020 to promote the self-supply of plasma medicines through a public-private partnership model. Under this innovative alliance, Grifols is helping develop the first integrated platform in the Middle East and Africa to supply plasma therapies on national and regional levels. Grifols Egypt currently has two operational plasma centers, with the aim of opening 20 centers in total. The company continues to make inroads on the construction of the remaining production installations, including plasma fractionation and purification plants, and analysis and storage facilities. These installations are expected to be operational by 2025. In the meantime, all collected plasma (up to a million liters per year) will be processed in Spain and returned to Egypt as finished product. The World Health Organization (WHO), Council of Europe and other institutions all agree on the urgent need for countries to increase their self-sufficiency of plasma-derived medicines for the sake of patients who need them. Under the umbrella of its “Self-sufficiency Program,” Grifols closely collaborates with countries to advance this crucial objective, helping them improve their healthcare systems and reduce their reliance on third parties.

2022 Consolidated Directors’ Report · 34 Donors and donations Donation regulations Plasma can be procured from whole blood donations (recovered plasma) or via plasmapheresis (sourced plasma). Plasma collection for fractionation is strictly regulated by various global healthcare authorities and good manufacturing practices (GMP). In the United States, the regulatory authority is the FDA and, in Europe, it is the European Agency for Medicine (EMA). The Plasma Protein Therapeutics Association (PPTA) defines and monitors additional quality standards as part of its voluntary IQPP (International Quality Plasma Program) certification. Plasma donation is an extremely safe process, with few to no side effects. Using the plasmapheresis technique, plasma is extracted from whole blood and blood cells, platelets and other components are returned to the donor. The body can regenerate the volume of collected proteins in less than 24 hours, a far shorter recovery compared to whole blood donations. Quality control in plasma donation centers Grifols’ donation centers follow the highest quality and safety standards and undergo ongoing regulatory inspections to guarantee the safety and quality of donated plasma. Plasma cannot be synthetically produced or created in a laboratory. Hundreds of donors and donations are needed to provide a single year’s supply of plasma-derived medicines for just one patient.

Grifols follows all the regulatory requirements of the health authorities. Additionally, has comprehensive processes, using the evidence based medicine approach, to establish the eligibility criteria an ensure whether a donor can donate. If medical evaluations reveal abnormal levels or irregular parameters, donors must postpone the donation process to ensure these are not indicative of an underlying health issue. Biomarkers include: O Irregular heartbeat O High body temperature O High or low hematocrit O High or low total protein O Lipemic plasma We protect donors’ health Grifols only uses plasma from qualified donors, never from occasional donors. Once deemed suitable, donors undergo physical exams and assessments of their medical, surgical, social and travel history. They are also subject to medical history before every donation. This information is recorded in the donor’s file, which is confidential and in compliance with Grifols’ data protection policy. Before each donation, a specialized Grifols staff member checks the donor’s vital signs and weight, as well as blood and plasma protein levels to confirm they can safely donate. Grifols’ regular medical assessments helps enhance the overall health and well-being of its donors, one of its corporate priorities. Qualified donors O Donate at least twice over the last 6 months O Maximum 2 times every 7 days O 18-69 years old O 50+ kg O Normal limits medical exam DOCUMENTATION O Valid ID picture: driver’s license, passport, etc. O Proof of Social Security Number O Proof of address Blood analysis with every donation O HCV, HBV, VHA, HIV and B19 virus detection O Hepatitis B, Hepatitis C and HIV antibodies O Other periodic tests Specific controls O Weight, blood pressure, pulse, temperature, anemia and protein levels Plasmavigilance: safe donations Grifols’ plasmavigilance data in 2021 indicates minimal donor adverse events (DAE)* in line with previous years. Only 0.2% of donations caused side effects per 10,000 donations. These levels are similar to those of previous years. Most adverse effects were minor, resulting in hypotensive events or phlebotomy-related injuries like hematomas. Severe reactions requiring medical assistance were extremely rare, representing only 0.005% of Grifols’ total donations. Data on donor side effects continues to confirm the safety of plasma donation. *Grifols publishes plasmavigilance data one year after the study following the criteria outlined in the “IQPP Standard for Donor Adverse Events” and the nine categories included in Plasma Protein Therapeutics Association (PPTA) guidelines. Hematomas 49.2% Hypotension 42.9% Other 3% Hyperventilation 0.5% Citrate reactions 1.7% Allergic reactions 1.6% Aeroembolism 0.06%

2022 Consolidated Directors’ Report · 36 Donor health is our top priority STUDY ON PLASMAVIGILANCE IN THE U.S. The rate of side effects from plasma donations via plasmapheresis is not significant More than 1.1 million donors – who together account for 72% of the U.S. source plasma collected for a four-month – participated in the first industry-wide, multi company study of the incidence, frequency and type of adverse effects of plasmapheresis. Promoted by the PPTA in cooperation with diverse industry firms, the study confirmed the overall safety of plasmapheresis. Following FDA standards of collection volumes and donation frequency, the rate of adverse events (AE) was 1.58 per 10,000 donations. Moreover, 90% of AEs were minor, such as hypotension and phlebotomy-related hematomas, and there were no reports of serious or severe adverse events. The scientific journal Transfusion published the study’s findings in 2021. IRON LEVELS Plasma donation has no effect on iron reserves This study found no loss of iron or decline in ferritin levels a a result of regular plasma donations – even in the case of long-term donors – as opposed to whole blood donations. In light of these findings, there is no need to monitor donors’ iron levels or recommend iron supplements. CHOLESTEROL LEVELS Research findings suggest that cholesterol levels may decline Apheresis or low-density lipoprotein extraction is used to treat patients with familial hypercholesterolemia. Similarly, the low-volume plasmapheresis used in plasma donations may also lower cholesterol levels in some donors. This research initiative examined the effect of plasmapheresis on total LDL and HDL cholesterol levels in a healthy plasma donor population. Based on its findings, total and LDL cholesterol levels may decline in donors with elevated baseline cholesterol levels following regular voluntary plasmapheresis. In donors with low baseline HDL levels, HDL cholesterol levels may increase. BLOOD PRESSURE The results suggest a beneficial effect for donors with high blood pressure Grifols conducted a study to determine the potential effects of plasmapheresis on blood pressure. The results suggest a beneficial effect among donors with high baseline blood-pressure levels, with significant decreases in both systolic and diastolic blood pressure when donation intervals are under 14 days. No decline in blood pressure was observed among donors with baseline normal blood pressure levels. + Access to all studies: Plasmavigilance: Source Plasma Joins the Call to Arms - Cho - 2021 - Transfusion - Wiley Online Library.

Its U.S. plasma donation centers are geographically diverse, with no particular concentration in specific areas. In its search for suitable sites for plasma centers, Grifols considers areas with a solid commitment to community progress, active chambers of commerce, and a strong vocation to advancing social progress. For Grifols, a community’s active participation in the plasma donation process is paramount to securing patients’ access to life-sustaining plasma-based therapies. Grifols’ plasma-center employees take proactive steps to forge ties with local residents by organizing educational, social and awareness-raising events on the vital need for plasma donations. Plasma centers also collaborate with local businesses and non-governmental organizations to help raise awareness on plasma and the manufacturing process of plasma therapies. The company considers other criteria when choosing where to establish plasma donation centers, including low viral markers, below-average crime statistics and community heterogeneity, critical to ensuring a diverse donor pool. Our commitment creates value A win-win commitment In 2022, Grifols once again measured the socioeconomic impact of its plasma donation centers in the United States and Germany using the input-output methodology.

In the case of rare diseases, training medical professionals is also key to reduce the time to diagnosis and improve the approach to these conditions. To this end, Grifols collaborates in various seminars and scientific conferences. O Greater awareness and visibility: Initiatives to give visibility to patient communities and commemorate their related International Days to forge community ties and help get their needs and challenges included on political agendas. Grifols takes part in creating and maintaining different communication channels and informational collateral. O Patient experience and welfare: Grifols collaborates with projects aimed at improving disease management and patient experience, including programs to facilitate the administration of treatments and promote healthy lifestyle and nutritional habits, among others. In 2022, the company supported Spanish hemophilia associations to offer patients physiotherapy services to address their musculoskeletal challenges and improve functional capacity, as well as psychological support programs for pediatric and adult patients of various associations. O Advocacy and access: Patient organizations ensure equity in access to treatment, and in the case of plasma derivatives, they also promote plasma sufficiency through a single donor-patient link. The shortage of plasma-based medicines remains an urgent global challenge despite a greater focus during the COVID-19 crisis. In 2022, Grifols continued to support plasma awareness and educational campaigns in Europe led by various primary immunodeficiency patient organizations. Plasma education program for European patient associations This initiative was launched in 2022 to educate and empower patient communities. Two editions of the program have been carried out with the participation of the main patient organizations in Austria, Germany, Spain and Switzerland. Building community Grifols strives to forge trusting relationships, educate and support the patient communities it serves. The “Open House” educational program, launched in the United States, is among the initiatives that reflects this commitment. In 2022, Grifols launched a program in Europe, bringing together, for the first time, 18 representatives from 10 different patient organizations in Spain in the first edition, and 12 representatives from 6 German-speaking organizations (plus two plasma donors) in the second edition, at the Grifols Museum and production plants in Barcelona. In addition to promoting education, “Open House” also aims to reinforce ties with patient associations by building a sense of community, promoting joint efforts and increasing their visibility. We support patients’ needs The Spanish Association of Primary Immune Deficiencies (AEDIP) leads the “Spanish Consensus for the Sufficiency of Plasma and Its Related Treatments” to promote a national strategy for plasma and plasma-based treatments in collaboration with patient associations, clinical experts, scientific societies, donor organizations and other market agents. The AEDIP aspires to make Spain a benchmark in the collection, management and use of plasma, ensuring patients a sufficient supply of plasma therapies and fast, fair access to treatment.

Before entering any commercial relationship with Grifols, third parties are subject to a thorough two-part verification process: a first phase, where Grifols establishes the legitimacy of the potential commercial transaction, and a second phase of due diligence, which includes an in-depth analysis of the third-party’s organizational structure, key employees, business approach and corporate reputation, among other aspects. Third-party contracts include current anti-corruption obligations, as well as an annex summarizing Grifols’ Anti-Corruption Policy. At least once a year, they are required to certify full compliance with the ethical standards outlined in this policy. In certain cases, third-party collaborators such as international distributors are also required to complete periodic online training on anti-corruption issues, for example, the U.S. Foreign Corrupt Practices Act (FCPA). The contracts with third parties also include a clause giving Grifols the right to perform audits and terminate commercial relations in the case of non-compliance with these norms. Internally, employees are responsible for constantly monitoring the day-to-day activities of the third parties under their management area. Both the potential violations alerts system and the continuous monitoring process aim at detecting possible red flags and, as such, manage and resolve these adequately and as promptly as possible.

2022 Consolidated Directors’ Report · 78 Ethics, science and innovation For Grifols, advances in the life-science domain cannot be separated from their essential humanistic component. Scientific progress must occur within an ethical and social framework. The company translates this commitment into action through the Víctor Grífols Lucas Foundation. Analysis committees in the Grifols Scientific Innovation Office supervise and monitor all issues related to clinical trials, including their ethical considerations. Grifols subscribes to three fundamental and universal principles, which together govern the ethics of its clinical trials as defined in its Human Rights Policy. Respect for people Respect for an individual’s ability to make decisions freely and independently, and protection of at-risk groups of people who may participate in research. In research processes, this principle is expressed through an informed consent form. Welfare Guarantee the health of people who participate in clinical trials. Risks must be minimized and benefits maximized for all participants. For Grifols, protecting people’s health takes precedence over professional and personal interests, the search for knowledge and research advances. Justice Research must strike a balance between benefits and risks. The principles and outcomes of research projects must be analyzed and participants must be selected homogeneously. Under this principle, participants are never exposed to unsafe situations to benefit another person. There is an obligation to safeguard the rights of vulnerable groups. + More information on Grifols’ Human Rights Policy: www.grifols.com

All clinical research led by the company or on its behalf complies with the standards defined in the International Conference on Harmonization of Good Clinical Practice (ICH GCP); the protection of human beings under the Declaration of Helsinki (1964); and applicable local laws and regulations. Clinical trials are described in a detailed protocol and sent to regulatory authorities and external ethics committees for evaluation. They only begin once a favorable decision has been confirmed. Participants submit a written, signed and dated informed consent form. The lead researcher (or assigned healthcare professional) provides appropriate information, resolves any doubts and gives potential clinical-trial subjects sufficient time to make an informed decision on their participation. Grifols implements standard operating procedures to maintain quality control and ensure the proper execution of clinical trials, and provides correct documentation and reporting of trial data in alignment with the protocol, the ICH GCP and applicable regulatory requirements. The company has additional procedures in place to enable clinical staff to detect and document potential fraud or misconduct. The company also has measures to safeguard subjects’ anonymity and promote the transparency of its clinical trial data. More information on the protocol, status and results stemming from Grifols’ clinical trials are disclosed on publicly accessible registries, including www.clinicaltrials.gov. In addition, the findings of clinical trials carried out within the framework of the European Medicines Agency (EMA) are registered on the EudraCT website. The company releases the findings of many of its clinical trials in international conferences and scientific journals. Responsible testing Grifols is committed to the responsible use of laboratory animals when animal testing is essential for the development of new life-saving therapies. Whether studies are carried out in university settings or in outsourced external laboratories, Grifols scientists work closely with regulatory agencies and the Institutional Animal Care and Use Committee (IACUC) to ensure the safe and ethical treatment of research animals. All facilities are approved by the competent authorities where research is conducted. In the United States, Grifols facilities are certified by the Association for Assessment and Accreditation of Laboratory Animal Care (AAALAC) or equivalent organizations and hold the highest accreditation possible for animal-testing laboratories. In Europe, laboratories comply with Directive 2010/63/ EU relating to the protection of animals used for scientific purposes and undergo country-specific inspections by the competent authorities. In parallel, the company also adheres to the “Alternatives and the 3Rs” (Replacement, Reduction and Refinement) protocol, which advocates (i) completely avoiding the use of animals or replacing them with alternative techniques; (ii) minimizing the number of animals used; and (iii) refining how experiments are performed to ensure animals suffer as little as possible. + More information: ClinicalTrials,gov and EudraCT,

2022 Consolidated Directors’ Report · 100 Fair compensation practices Grifols is firmly committed to effective equality by providing equal opportunities and equal pay regardless of gender. Every year, the company carries out a gender pay gap analysis, both adjusted and unadjusted, as part of its continuous efforts to promote equality. In 2022, Grifols received external support from the global consulting firm EY to ensure the utmost rigor and transparency in the analysis. The unadjusted wage gap is calculated as the percentage differential between men’s and women’s gross wages per hour worked. That said, the adjusted wage gap is considered a more accurate measure since it employs econometric models to isolate factors in men’s and women’s wages stemming from differences in socioeconomic attributes (ex. age, seniority, geographical area and educational level) and job characteristics (work schedule modality, type of activity and professional category). This report examines the gender pay gap in Spain, the United States, Ireland and Germany, which combined account for over 90% of the group’s employee base. Based on the 2022 World Economic Forum’s Global Gender Gap Report, Grifols’ unadjusted pay gap is below national averages in Spain, Germany and Ireland. The company’s results by professional category highlight its progress in increasing the presence of women in leadership roles and advancing pay equality, with concrete metrics outlined in the 2021-2023 Global Diversity Plan. Guided by these objectives, Grifols has bolstered the proportion of women in senior positions in recent years. In 2022, female representation in the Directors category grew to 41.1% compared to 34.8% in 2019. In addition, the Grifols 2030 Agenda includes a target of 50% women in Senior Management roles, which at the close of 2022 stood at nearly 39%. The company foresees a positive impact on wage gap differentials as a result of this progressive upswing in women-led leadership roles. For Grifols, another critical factor in advancing wage parity is bolstering women’s participation in STEM (Science, Technology, Engineering and Mathematics), a field where they have been traditionally underrepresented. The company spearheads various initiatives and measures to identify STEM roles and foster greater access for women. Equal pay between men and women + More details on remuneration data are available at the end of this chapter.

In addition to its action plan to advance these two aforementioned factors -both directly related to the gender pay gap- the company has also rolled out measures to improve its recruitment, salary review and promotion processes, ensuring these reflect individual performance evaluations based on common, transparent and gender-neutral criteria. As part of Grifols 2030 Agenda, the company aims to ensure women account for 50% of candidate interviews for managerial roles and higher. In parallel, it also promotes flexible work schedules for both men and women and professional development actions to bolster its pipeline of female talent for top-leadership positions. Grifols worked to achieve greater female representation in leadership roles – women hold 41% of director positions and 33% of board membership – while narrowing its gender pay gap close to parity.

Pay-gap declines in the Director (-10.7%) and Management (-1.9%) categories were especially noteworthy. The company continued to adapt its existing equality measures to the new requirements defined in Royal Decree 902/2020 of October 13, 2019, which included additional transparency obligations for compensation audits. Grifols carried out a pay analyses in line with this new regulation, which was presented to the Equality Plan Negotiating Committee in Spain. This study complements the gender gap study and provides further information to reinforce the company’s action plan. In 2022, the unadjusted pay gap in Spain stood at 38.4%, far higher than Grifols’ 12.1% gap. This gap has progressively narrowed from the 12.4% reported in 2021 and 14.3% recorded in 2020. Worth highlighting were Grifols’ narrower pay gaps in its Directors (-3.9%) and Management (-1.1%) categories. THE U.S. Gross gap very close to the national parity In 2022, Grifols continued to advance pay parity and promote women’s access to leadership roles, reducing its adjusted pay gap in the U.S. to 0.9%. Declines in the adjusted pay gaps in Directors (-1.3%), Senior Professional (-2.3%), Professional (-1.2%) and Administrative staff/ Manufacturing operators (-1.0%) categories were particularly noteworthy. The country’s unadjusted pay gap fell significantly last year, from 32.2% in 2021 to 22.8% in 2022. In recent years, the U.S. unadjusted pay gap was especially high due to cyclical circumstances stemming from the healthcare crisis. While impacted by a challenging U.S. labor market, Grifols reduced the gross pay gap by 3.5% in 2022 to 24.6% after effectively implementing a series of measures. IRELAND Gross pay gap below the national average In 2022, the adjusted gap stood at 2.8%. The employee pool grew by 21.5% last year, attaining greater female representation in the Directors, Management and Senior Professional categories. In light of the sharp upturn in total employees, the company is unable to conduct an adjusted pay-gap analysis with sufficient statistical reliability, both in overall terms and by professional categories as the 2022 sample is not comparable with 2021 levels. The unadjusted pay gap for Grifols in Ireland was 15.8%, compared to the country’s overall 29.7% gap. The company’s 2022 figure reflects a 1.6% decline compared to 2021, reflecting its ongoing efforts to ensure fair remuneration conditions for men and women when performing the same role. GERMANY Gross pay gap well below the national average In Germany, Grifols’ adjusted pay gap is 1.4%, and women hold 56% of team leadership roles, a 1% upturn over 2021. The unadjusted pay gap is 14.5%, far below the 41.4% national average. In 2022, Germany’s pay gap grew by roughly 2.8% in 2022, while Grifols’ gross pay gap decreased by 3.8%.

SOCIAL RELATIONSHIPS: BUILDING TRUST Social dialogue For Grifols, engaging in social dialogue with worker representatives is critical to jointly address transversal issues requiring collective bargaining in its various workplaces. In Spain, the labor-relations system establishes two types of representation in companies: trade union representation and unitary or elective representation. These people include members of trade unions, company committees and personnel delegates, with whom Grifols holds regular meetings to address issues affecting the workforce. In other countries such as France and Germany, the company routinely meets with workers’ legal representation. In Italy, company decisions that could impact collective working conditions are discussed with trade union organizations. Collective labor agreements Grifols’ employees in Spain, Germany, Italy, France, Argentina and Brazil work under collective agreements. In 2022, 4,474 employees were covered by these agreements, representing 18.7% of Grifols’ workforce. In the United States, industry-level collective bargaining does not exist and is carried out at the company level. The Taft-Hartley Act regulates industry-specific benefit plans and provides that federal courts have jurisdiction to enforce collective bargaining agreements. Workers representation committees In Spain, Chile and Germany, where labor committees are established by law, Grifols assigns managers to oversee the prevention of occupational health and safety risks. In 2022, the majority of employees in Spain were represented by a joint committee comprised by employees and occupational health and safety managers. In Chile and Germany, 100% of employees were represented by these committees. There is no formal representation in the remaining Grifols subsidiaries. In these markets, the company regularly communicates and consults with its specific workforces, which establish committees that welcome employees’ participation and proposals. Each subsidiary defines the frequency of these meetings and subsequent follow-up of the committee’s specific plans, actions and measures.

These include a 24-hour physiotherapy service in Spain to prevent musculoskeletal injuries, evaluate employees’ psychosocial risks and develop specific wellness plans. The company also carries out awareness sessions, return-to-work interviews following extensive leaves, and communication protocols for employee absences.

Diverse environmental programs, as well as oversight by the Sustainability Committee, Sustainability Steering Committee and Environment Committee, ensure these commitments are implemented in line with the Sustainability Master Plan. The Chief Industrial Officer (CIO) is responsible for environmental performance and climate change issues. Finally, the Risk Committee, which reports to the Board of Directors, is responsible for developing the risk management model and overseeing the most relevant risks, including those related to climate change. Risks and opportunities This process involves updating the climate risk map and analyzing the qualitative and quantitative resilience of the company’s strategy based on a potential maximum rise of 2°C. A simulation of the climate scenarios proposed by the IPCC was carried out to reflect the SSP2-RCP4.51 scenario. The exposure study included Grifols’ most relevant industrial facilities and plasma centers. An assessment was made to evaluate the estimated time frame, the probability of occurrence and the inherent and residual potential impact for each of the 29 climate risks detected. While the risks and opportunities identified are not yet significant, the company nonetheless reassessed the suitability of the management plans defined in 2022. Strategy Business optimization and innovation are two fundamental cornerstones of Grifols’ corporate strategy. Both are underpinned by objectives related to climate change, which are set out in the company’s Environment Program and promoted through various corporate policies, including climate action. Climate risks and opportunities form an integral part of Grifols’ strategy and decision-making process. Climate risks and opportunities have a direct impact on Grifols’ business and financial strategy and planning, especially in areas related to industrial, operations, products and services. For this reason, climate change is included in operational cost planning and capital allocations, mainly in terms of implementing eco-efficiency and emission reduction measures. Grifols fully abides by existing and future regulatory requirements, implementing procedures to ensure compliance (EV-SOP-000004), which undergo biannual audits. The company’s Environmental Committees monitor these processes and define any further action measures. Metrics and targets Grifols evaluates and monitors when it has reached Environmental Plan targets2 and their impact on mitigating relevant physical risks and leveraging key opportunities. Regarding the link between the remuneration policy and the performance indicators, the Energy Manager is offered incentives related to improving the energy efficiency of company processes. Finally, it should be noted that the company is not subject to any emissions trading scheme. Grifols participates annually in the Carbon Disclosure Project (CDP)3, a program which assesses the organization’s strategy and performance in terms of climate change.

2022 Consolidated Directors’ Report · 2022 Informe Anual Integrado y de Sostenibilidad · 132 132 Emissions Grifols uses the international standard GHG Protocol Corporate Accounting and Reporting Standard methodology to calculate its carbon footprint and identify the greenhouse gas emissions (GHG) generated by its business activity. The data reported includes all Grifols’ global facilities, as well as acquisitions in 2022 and commercial subsidiaries with more than 10 employees. Since 2011, Grifols has published its Scope 1, Scope 2 and some Scope 3 CO2 emissions, where data was available. Throughout 2022, Grifols calculated 2021 figures for all Scope 3 emissions internally, also identifying those considered irrelevant. This year, those for 2022 have been calculated. Key impacts: O Scope 1 improved by 36% vs 2021 to 95,000 tCO2e due to lower natural gas consumption primarily at Biopharma’s Barcelona cogeneration facility, as well as a 75% decrease in refrigerant gas leaks, mainly in the U.S. facilities. O In Scope 2, emissions decreased by 30%* to 105,000 tCO2e due to a significant rise in renewable electricity consumption, accounting for 26% of the total. Electricity consumption rose slightly, although below the increase in production. O Scope 3 exceeds 1.4 million tCO2e. Category 1, Purchase of goods and services accounts for more than 50% of emissions, followed by transportation contracted by Grifols (15%) and capital investments (14%). O By geographic area, more than 70%** originate in the U.S., where 67% of Biopharma’s activity takes place. The remaining 30% is divided between Spain and the rest of the world. O In all plants, air emissions of other pollutants such as NOx, CO and SO2, generated by the natural gas combustion in boilers and cogeneration engines, are below the limits established by the relevant environmental authorities. Grifols is reducing its GHG emissions by increasing its use of renewable energies, which already account for 26.4% of its electricity consumption. In 2022, Grifols’ 10-year power purchase agreement (PPA) to acquire clean energy from RWE’s Casa Valdés photovoltaic plant became operational, furthering the company’s efforts to reduce its carbon footprint. Under the agreement, Grifols will acquire 26 million kWh per year from RWE, avoiding the emission of 5,200 tones of CO2. In the United States, more than 80 million kWh of electricity was consumed from renewable sources, while in Ireland more than 11.5 million kWh. SCOPE 1 Direct emissions: generated by the business activity itself. Includes direct emissions generated by combustion sources or direct greenhouse gas (GHG) emissions. SCOPE 2 Indirect emissions: generated by energy production, mainly electricity, consumed by the organization. SCOPE 3 Other indirect emissions: generated by other supplier companies throughout the life cycle of our products or services. Includes business travel, employee transportation and commutes, raw materials, among others. We measure the scope of our emissions (tCO2e) Committed to renewables 2020 2021 2022 *Scope 2 (location-based). A change has been made in calculating Scope 2 emissions. The cogeneration plant at the Barcelona facility discharges the electricity generated into the grid and Grifols purchases the electricity it needs at any given time from the grid. Previously it was considered that the emissions generated for the production of this electricity were already accounted for through the combustion of natural gas from cogeneration and therefore the electricity produced and sold was discounted from the electricity consumed. In 2022, both the emissions from natural gas for cogeneration and those corresponding to all the electricity purchased have been accounted for. ** Scope 1 + 2 TOTAL EMISSIONS 200,310 tCO2 e Scope 1 and 2 -32.8% vs 2021 in absolute value Scope 1 Scope 2 (Location-based) Scope 3 111,435 127,596 1,416,451 1,323,454 148,129 150,276 95,242 105,068

However, compared to 2021, it increased by 44%. The number of videoconferences in 2022 was 31% higher than in 2019 and 3% lower than 2021. New ways of working have helped to minimize travel among Grifols’ various global work centers. Increase in remote work Grifols “Flexibility for U”, implemented in 2022, regulates the rules on remote work. Last year, remote work increased by 35% compared to 2021, averaging over 2,900 connections per day. Optimizing logistics Grifols has been working to optimize its plasma transport network in Europe since 2021. Through these efforts, the company has reduced its contracted transport services by over 290,000 km. These measures include adjusting the frequency of plasma collection routes in European workplaces; promoting full truckloads between plasma collection points, warehouses and the Barcelona manufacturing complex; increasing the storage capacity of plasma collection containers; and using larger U.S. pallets to maximize storage and transport, among others. Minimizing the impact of employee commutes Grifols works to reduce the impact of emissions resulting from employee commutes. The Parets del Vallès facility offers an employee bus service to coincide with different shift times, while in North Carolina, Grifols co-funds a shared transport service. In recent years, electric vehicle charging stations have been installed in the main workplaces.

Spain consumed 26.5 million kWh of renewable electrical energy In 2022, Grifols’ 10-year power purchase agreement (PPA) with RWE to acquire clean energy from its Casa Valdés photovoltaic plant became operational. In addition, Biopharma’s photovoltaic power plant in Barcelona continued to create energy for self-consumption, generating 311,399 kWh in 2022. In total, 454,381 kWh of photovoltaic energy was generated at Biopharma and Others’ own facilities for self-consumption in Barcelona and Murcia. Renewable electricity agreements in the U.S. and Ireland By region, 71% of the group’s electrical energy is consumed in the United States, home to several of its industrial complexes and the majority of its plasma donation centers. In the U.S., 80 million kWh of electricity was consumed with a guarantee of renewable energy, and more than 11.5 million kWh in Ireland. Together, they account for 20.3% of electricity consumption. The company is working to reach PPA agreements in the U.S. in the coming years. COGENERATION 6% of total electricity consumption from the cogeneration plant in Barcelona Biopharma’s Barcelona installations include a 6.1 MW cogeneration plant that generates electricity sold back to the grid, as well as producing useful heat for Grifols’ own facilities. This plant was not operating at full capacity in 2022, generating 27.6 million kWh of electricity (33% less than 2021) and 20.6 million kWh of useful heat. Artificial intelligence (AI) is helping Grifols’ facilities work much more efficiently. Integrating this technology has led to a more than 15% fall in energy consumption in air conditioning in the production rooms of the Parets del Vallès (Barcelona, Spain) Diagnostic Unit. Air conditioning is one of the company’s main sources of electricity consumption, and technology can offer ways of reducing it. This led to the launch of the “Energy efficiency through (artificial intelligence)” pilot project in 2022. The company is working to replicate this initiative in other areas with high demand for air conditioning and also in the production of cold for Biopharma’s fractionation and purification processes. Artificial intelligence to reduce consumption

2022 Consolidated Directors’ Report · 138 Circular economy Grifols’ environmental management is based on the concept of the circular economy, which endeavors to reduce the consumption of raw materials, water and energy sources in the production cycle. The company prioritizes the efficient use of resources and works to reduce waste by focusing on the different stages in the product life cycle. The goal of this strategy is to embrace the transition to a low-carbon economy and minimize the impact on climate change. • Rationalization of cardboard, plastic and caustic soda consumption • Maximum utilization of raw materials • Promoting local suppliers • Route optimization • Environmental criteria in engineering projects • Eco-design of equipment (diagnostic & engineering) • Environmental criteria in R&D • Container and packaging design • Residual waste recovery • Energy recovery from waste • Anaerobic digestion • Zero Waste to Landfill initiative • In-house treatment of wastewater • Minimization of atmospheric emissions • Water recovery systems • Optimized water consumption • Energy efficiency • Renewable energy consumption • Cogeneration plant • LEED/Green Globes building certification • Recycling of recoverable waste • Internal reuse of ethanol • Recovery of intermediate products • New biological products marketed by the Bio Supplies Business Unit • Optimization of packaging • Recycled/recyclable packaging materials • Certification of transport companies • Optimization of routes and means of transportation • SIGRE – Integrated Management System for drugs out of specification • Collection and management of electric and electronic equipment placed in the market • Reuse of ethanol in production processes • Intermediate products: PEG + sorbitol • Grifols Engineering machine manuals • Equipment manuals (diagnostic) ALCANCE INTERNO Design Collection Recycling Residual Waste Raw Materials Distribution Production, Remanufacturing Consumption, Use, Reuse, Repair Economía circular

Ethanol, polyethylene glycol and sorbitol are primarily used in the fractionation and purification process of the different plasma proteins. Plasma fractionation enables proteins with therapeutic properties to be extracted and subsequently marketed by Grifols. This process involves subjecting the plasma to successive temperature, pH and ethanol concentration adjustments, each of which facilitates the precipitation of one of these proteins. In the Diagnostic Business Unit, the main raw material is the plastic used in the production of its diagnostic cards (DG-Gel®), in addition to the base plates to manufacture auto-analyzers, and red blood cell reagents for diagnostic kits. Maximum repurposed of plasma Most of the plasma unsuitable for fractionation is marketed through Bio Supplies to produce diagnostic and analytical reagents for research purposes. By 2022, more than 135,000 liters of plasma had been sold, resulting in the annual reuse of 135 tons of raw materials and consequently, the same volume in waste reduction. The remaining plasma is discharged in authorized incineration plants with energy recovery. Once all the plasma proteins for therapeutic purposes have been obtained, the remaining paste is disposed of as waste and managed according to its composition and country: plants producing substitute solid fuel for pastes with a high calorific value; anaerobic digestion for the production of biogas; composted, controlled landfills for non-hazardous waste; or autoclave treatment and subsequent landfill disposal. Management of intermediate products A solution of polyethylene glycol (PEG) and sorbitol is used to separate and obtain Flebogamma® DIF intravenous immunoglobulin. After use, this solution is concentrated at Grifols’ Barcelona facilities and marketed to additive manufacturers for use in the cement industry. By 2022, approximately 33,000 tons of aqueous solution of polyethylene glycol and sorbitol had been transformed into 11,136 tons of product sold as raw material for other uses. + More details on raw material consumption are available in the tables in Chapter 9.

This treatment process is carried out in a highly efficient reactor that reduces 85% of the organic pollutant load in the absence of oxygen, with very low energy consumption, generating biogas of renewable origin. Once treated, this biogas is used as fuel for the plant’s steam production boilers, thus reducing natural gas consumption and CO2 emissions into the atmosphere. This facility will double the plant’s current wastewater treatment capacity in order to reduce the current final discharge parameters or maintain them in the event of production increases. At Biopharma’s North Carolina facility, a new wastewater treatment plant is in the process of being validated. This uses membrane bioreactor (MBR) technology and a sludge treatment line to improve discharge parameters. This plant, which will begin operating in 2023, is set to treat between 3,500 and 7,000 m3/day to serve the facility for the next 15 years. Wastewater and discharge management Grifols adheres to all applicable national and local regulations and permits regarding the disposal and treatment of wastewater at its installations. All wastewater is sent to local sewage systems, where it is treated by municipal or regional facilities. Grifols’ industrial plants pre-treat the water to suitably purify it before its disposal, and all are located in areas where the local authorities monitor water discharge. Manufacturing plants with environmental management systems and/ or certified companies have instructions on how to prevent, control and monitor the quality of wastewater. Commercial offices and warehouses discharge wastewater into the municipal sewage system. In 2022, 2.3 million m3 of wastewater was discharged to public sewers. In U.S. plants, stormwater is conveyed to public waterways, including the Los Angeles River, the Neuse River and San Francisco Bay. Approximately 23% of water is consumed in auxiliary processes -such as cooling towers- or incorporated into the product, while 77% is discharged to the sewer. In 2022, the Barcelona and Clayton (North Carolina) facilities treated 873,892 m3 of wastewater using biological systems prior to discharge, representing 37% of total discharge and an improvement over 2021. Projects are underway to expand these treatments at both plants, as set out in the 2020-2022 Environmental Plan. In water-stressed areas, the distribution of discharges corresponds to water consumption, with no significant variations from previous years. Chemical Oxygen Demand (COD) is the most significant discharge parameter in Grifols plants. This is defined as the amount of organic and inorganic matter susceptible to oxidation. In 2022, 2,525 tons of COD were discharged, most of which corresponded to Biopharma’s production facilities. In addition, 357 tons of suspended solids were discharged. Grifols does not work with genetically modified organisms or with products capable of generating persistent organic compounds, and consequently, generates no discharge of this nature. The contribution of nitrogen or phosphorous to the wastewater is insignificant since it comes mainly from sanitary and non-production-related discharges. In 2022, Biopharma’s facilities in Barcelona were fined € 750 for exceeding one of the established discharge parameters. 23% water incorporated into the product and used or consumed in auxiliary processes 77% is discharged to the sewers Total water discharge 2,3 M m3 -4,2% 48% of Biopharma’s wastewater is treated prior to being discharged -8% COD discharge and -17% suspended solids discharge

It therefore maintains the highest rating in the “Zero Waste to Landfill Gold Operations” certification. The facilities in Spain have made headway in waste recovery by changing the final destination of a large part of general waste, which is currently managed as solid recovered fuel. All recoverable waste fractions are now managed separately, and only waste that cannot be recovered or recycled due to its composition and applicable legislation is sent to landfill or incinerated. This change has reduced the amount of waste disposed in landfills to 29%, compared to 31.4% in 2021. Waste is sent to authorized waste management companies and regular audits are performed by independent specialist auditors. Medication waste management Most Grifols products are used in hospitals, which have their own recycling and disposal criteria established by local health authorities. Grifols products designed for domestic use are dispensed in pharmacies or by hospital suppliers, each of which has its own procedures regarding the safe collection and disposal of self-injectable devices. Grifols participates in various drug waste management programs. • Spain: the SIGRE program manages the collection of household medicine packaging and waste to ensure it is safely treated to protect the environment. • United States: the Pharmaceutical Product Stewardship Working Group (PPSWG) serves as a platform to organize and present science-based data on safe disposal practices for pharmaceuticals and implements industry efforts to raise awareness of appropriate disposal methods. For medicines that end up not being marketed or returned, Grifols uses waste handlers who separate and classify medicine packaging (paper, cardboard, glass, plastics, etc.) to be recycled by specialized companies. The medicines themselves are disposed of through an authorized waste management company, using incineration methods and incineration with energy recovery. Grifols’ main products are plasma medicines for intravenous or intramuscular administration in healthcare centers. The biological origin of plasma medicines limits their impact on the environment since waste is primarily generated from their containers and packaging, most of which can be recycled. The drug package leaflets indicate the correct waste management practices for country-specific legislation.

2022 Consolidated Directors’ Report · 144 Projects underway Under these programs, several different voluntary projects and activities are carried out throughout the year, aimed at biodiversity protection and for educational purposes. There are currently seven active projects underway: Biodiversity Grifols is firmly committed to protecting biodiversity on its own land through the Grifols Wildlife programs. These include the launch of various initiatives in the Clayton (North Carolina) protected natural area, and the collaboration agreement in the Besòs river basin in Barcelona. The collaboration agreement for the promotion of actions in the Besós River basin in Barcelona for the period 2020-2022 is also still in force. Natural protected area in North Carolina Grifols owns over 121 hectares of forest adjacent to its production facilities in Clayton, North Carolina. This is an ideal habitat for many aquatic and terrestrial species and is certified by the Wildlife at Work and Corporate Lands for Learning programs, both of which were launched by the Wildlife Habitat Council (WHC). Conservation projects* carried out in 2022 include: O Installation and maintenance of bird houses for bluebirds, taking into account their territorial nature. Contributes to favoring the nesting, breeding and shelter of this native species. O Protection of an extensive wooded area adjacent to the Grifols facilities as a habitat for wildlife, which was land earmarked for development, maintaining it as a recreational area for environmental education for the workforce. In 2022, bridges were repaired and made accessible for disabled users; the trails were cleaned and generally maintained; and invasive plant species were controlled and removed. Contributes to preserving forest-dependent fauna, plant diversity, and eliminating invasive species in the area. O Continuation of the internship program for students at North Carolina State University (NCSU) to supervise and manage the Grifols Wildlife Habitat Area, a unique space for environmental and conservation internships. Interns are responsible for coordinating projects related to habitat (forest, prairie, wetlands, etc.) and species (pollinator gardens), as well as monitoring and designing improvement initiatives. Internships have been evaluated since 2020 and are supported by Grifols personnel. Contribution in 2022: 380 hours of student time. O Management of prairie flora and fauna, including the installation of nesting boxes for bluebirds and bats and the elimination of non-native plant species. Contributes to preserving dependent fauna, plant diversity in the area and eliminating invasive species. O Improvement and maintenance of a pollinator garden for the development of five active beehives. In 2022, a small fence was placed around the garden, and a solar pump and hoses installed.

Several projects were launched in 2022, including research studies to monitor the otter and fish at the RIVUS Observatory, and environmental education, communication and training initiatives. Otter monitoring In 2014, images of an otter were captured in the Tenes River. Shortly thereafter, Grifols signed a collaboration agreement to carry out more research on this species in the Besòs and Tordera river basins. Both rivers are considered the last frontiers of expansion and recovery of the otter in Catalonia after practically disappearing at the end of the last century. Over the last two years, the project has reached its core objective: otters have reproduced in both basins for the first time since becoming extinct in the region. By 2022, seven otter families had been sighted, with an estimated population of at least 34 otters between both basins. The large volume of data and the knowledge generated since the project’s inception has allowed for more in-depth research on otter population trends and dynamics. In 2022, research began to identify the necessary preservation spaces and habitat elements to conserve otter populations and their ecological community for the long term. Fish monitoring Fish are excellent bioindicators of the quality of river systems, and electrofishing is the primary research method used to study their populations. The RIVUS Observatory is one of the few long-term monitoring organizations for Iberian inland fishes. This monitoring is exceptional in Spain in terms of length of the time series and breadth of the taxonomy groups in question. Sampling was carried out throughout 2022 at 22 stations (12 in the Besòs basin and 10 in the Tordera basin), including three annual campaigns covering spring, summer and autumn seasons. The data collected will advance knowledge of fish communities in both areas and provide continuity for their monitoring. Education, promotion and communication In addition to promoting research and initiatives on otters and fish species, Grifols also participated in various environmental education, promotional and communication activities, including the production of audiovisual material, multimedia awareness campaigns, promotional materials, and teaching sessions in academic institutions, universities and conferences.

The plan includes the optimization of plasma costs and operations, streamlining corporate functions, and enhancing other efficiencies across the organization. It also includes a workforce optimization to be implemented in 2023 that will affect approximately 8% of the company’s employees, primarily in the U.S. plasma operations. The Group estimates one-time restructuring charge of approximately EUR 140 million to be accrued in the first quarter of 2023. Grifols’ foreseeable evolution Grifols is a large consolidated company with robust fundamentals and a clear vision to strengthen its position moving forward. In the coming years, its strategic road map centers on: efforts to drive corporate growth, in which increased competitiveness will continue to play a pivotal role; innovation, with a strong focus on developing a differentiated product portfolio; customer orientation to effectively respond to the evolving needs of patients and healthcare professionals; continued global expansion; solid human resources policy based on ongoing talent development, continuous training, and the development of transversal initiatives and teams; and promoting sustainability to continue reinforcing a long-term business model that integrates and promotes environmental, social and corporate governance (ESG) issues. As part of this process, the company carried out an in-depth analysis of its business areas and functions to discern where it could achieve greater organizational efficiencies and profitability. In this way, it aspires to not only bolster its financial performance, but amplify its agility and response capacity. The result is a wide-ranging operational improvement plan to be implemented by 2023 along three core dimensions: 1) Plasma collection, including reorienting its U.S. plasma operations to promote a more efficient, modern, reliable and accessible network of plasma collection centers for donors. Grifols will consolidate and relocate some of its U.S. plasma donation centers, and close underperforming sites. In parallel, the company is working on forging a digital plasma-collection ecosystem to eliminate bottlenecks and offer donors a quicker and more agile service to enhance the donor experience. It also plans to streamline plasma-collection organizational structure to make it more agile, efficient and results-oriented. The company believes the cumulative effect of these changes will contribute to reducing donor compensation. 2) Restructuring of corporate functions to optimize and simplify reporting structures, automate workflows, consolidate suppliers, implement shared services across all business units and, in some cases, eliminate duplicate positions. 3) A general operational efficiency initiative focused mainly on global purchasing, logistics and optimization of office space (non-industrial). Grifols continues to make inroads on its long-term sustainable growth strategy, focused on improving its cash flow and expense profile, reducing debt, capturing new sales opportunities, fully exploiting Biotest synergies, and streamlining its organizational structure. In addition, it continues to evaluate alternatives to reduce its debt level.

2022 Consolidated Directors’ Report · 162 Tax value distribution Grifols’ various activities generate direct and collected taxes, paid to global tax authorities. In general, these highly integrated activities can be classified into net interest, wages and salaries, taxes (borne and collected) and shareholder value. The distributed tax value (DTV) ratio shows the percentage of the total value generated by Grifols allocated to pay taxes borne and collected from Public Administrations. Contribution by geographic area Grifols’ tax policy establishes a responsible approach to ensure good tax practices, embracing principles consistent with those set forth in OECD Guidelines for Multinational Enterprises (2011). It expressly states that Grifols has no presence in territories classified as tax havens, and that its business transactions with third parties in these territories or any other territories form part of its ordinary business activity. Grifols is taxed on the profits generated in each country it operates. Spain, the United States, Ireland, Germany and United Kingdom account for more than 70% of the Group’s global revenue, and its main industrial and R+D+i facilities are primarily located in these countries. Taxes borne Taxes Collected Shareholder value Net Interests Wages and salaries net of taxes collected 10% 11% 51% 15% 13% 40% 14% 13% 18% 15% DTV increases by 7% rises from 25% to 27% globally That is, 27% of Grifols’ value creation was paid to the public treasury through taxes borne (14%) and collected (13%). Out of every €100 of value generated in 2022, Grifols paid €27 in taxes.

While this situation generates a negative accounting result, it does not affect the payment of taxes. This decline is considered non-deductible for tax purposes, hence, does not affect the Group’s taxable income in Spain. Excluding its impact, Grifols’ tax contribution ratio in Spain would be close to 100%, representing an increase over 2021.

2022 Consolidated Directors’ Report · 170 Materiality During 2021 Grifols anticipated the effectiveness of the new GRI (Global Reporting Initiative) and prepared a materiality study in accordance with the new universal GRI standards, specifically GRI 3: Material topics, which has become effective this year. With the aim of continuing to improve and anticipate regulatory requirements, this year Grifols has extended its materiality assessment to include the financial view. Thus, obtaining a double materiality and aligning itself with the recommendations of EFRAG (European Financial Reporting Advisory Group). Both views and the result obtained are explained below: MATERIALITY BY IMPACTS Materiality by impacts performs an inside-out analysis, analyzing the impacts caused by the company on the environment. This study allows the company to know the material issues that represent the most important impacts that the organization generates, or may generate on the economy, the environment, and people, including Human Rights. The methodology followed for this study is based on the methodology presented by GRI 3. It is divided into two blocks, on the one hand, the identification and evaluation of impacts and on the other hand, the determination of the material issues to be reported. Within each of these, the following phases are broken down: 1.1 Understand the organization’scontext 1.2 Identify actual and potential impacts 1.3 Assess the significance of the impacts 2.1 Prioritize the most significant impacts for reporting 2.2 Determination of material aspects PHASE 1. IDENTIFY AND ASSESS IMPACTS ON AN ONGOING BASIS PHASE 2. DETERMINE MATERIAL TOPICS FOR REPORTING This study has identified Grifols’ material topics based on the impacts generated or likely to be generated by the organization. 1. IDENTIFY AND ASSESS IMPACTS ON AN ONGOING BASIS 1.1. Understand the organization’s context The entire value chain of Grifols’ main businesses is analyzed. Identifying the activities carried out by the company and the commercial relationships, taking into account the company’s stakeholders and business partners, as well as the sustainability context in which they occur. 1.2. Identify actual and potential impacts In order to identify the positive and negative impacts that Grifols can generate with its activity, an analysis of the press, sector studies and reports published globally and nationally on the sector is carried out. At the same time, a benchmark is carried out with other companies in the sector. Based on this analysis and the results of the previous analysis, a list is drawn up of the positive and negative, direct and indirect impacts generated or likely to be generated by Grifols’ activities. 1.3. Assess the significance of the impacts For each of the impacts listed above, the following is analyzed: - The probability of that impact happening (for current impacts this indicator is not evaluated). - The severity of the impact, considering: – Scale: level of severity of the impact. – The scope, extent of the impact, e.g., the number of individuals affected or the magnitude of environmental damage. – Irremediability: the degree of difficulty involved in counteracting or correcting the resulting damage. The results of this assessment are validated by both Grifols managers and industry experts GRI 3-1

DETERMINE MATERIAL TOPICS FOR REPORTING Based on the results of the evaluation of the previous phase, the importance of the impacts is analyzed according to their probability and severity, which allows us to identify those impacts with the greatest importance. The most important impacts are grouped and correlated with the different material issues, thus obtaining a first list of material issues for Grifols according to the materiality of impacts. FINANCIAL MATERIALITY Financial materiality consists of an analysis from the outside in, analyzing the risks and opportunities that affect or may affect the organization. In order to carry out the study from a financial perspective, Grifols analyzes whether the environment triggers, or may trigger, significant financial effects for the organization. In other words, whether the environment generates or may generate more significant risks or opportunities that influence or may influence future cash flows and, therefore, the value of the company in the short, medium, or long term. The methodology is divided into two phases: 1. IDENTIFICATION OF RISKS AND OPPORTUNITIES The first step is to understand the context of the company and the sector. For this context analysis is considered. - The impacts analyzed in the materiality by impacts of the previous year. - They are associated with the issues defined by EFRAG and, - The main resources and business relationships necessary for Grifols’ activity are recognized, analyzing all the company’s business divisions. Once the resources and business relationships have been identified, the following is analyzed - Trends in the sector and Grifols’ main resources. - The regulatory, geopolitical and climatic context that may affect both Grifols directly and its resources or business relationships. This analysis makes it possible to identify various risks and opportunities, these are classified according to. - Whether they are risks or opportunities, - Whether they are current or potential, and - Whether they may occur in the short, medium or long term. 2. ASSESSMENT OF RISKS AND OPPORTUNITIES In Phase II of this materiality analysis, Grifols evaluates the risks and opportunities. For the evaluation, the probability of occurrence of the potential risks or opportunities and the magnitude in the event of their occurrence are assessed. The followin g ranges are used to assess the probability: - Very unlikely - Unlikely - Unlikely or improbable - Probable - Very probable And finally, to value the magnitude, the following ranges are used: - Minimum - Low - Significant - Very significant - Critical The results of this assessment indicate the relevance of the risks or opportunities. The results are validated both by Grifols managers and by experts in the sector. The selected risks and opportunities are grouped and correlated with the different material issues, resulting in a list of material issues for Grifols according to the financial vision. GRI 3-1

Grifols’ risk control and management policy includes rigorous systems to prevent, control and manage its exposure to risk, providing greater security to patients, donors, employees, shareholders, customers, suppliers and other stakeholders. This policy is carried out through a comprehensive risk control and management system based on COSO (Committee of Sponsoring Organizations of the Treadway Commission) principles, and includes governance and culture, strategy and objectives, performance, review, information, communication and reporting. Through the Audit Committee, the Board of Directors oversees the effectiveness of the risk control and management system. The Audit Committee is assisted by the Internal Audit Department in these functions, providing a guarantee in relation to management of risk processes. The corporate risk committee oversees the management’s responsibilities with regard to assessing, monitoring and controlling risks.

Therefore, the risk management function at Grifols is independent of commercial functions and other departments, and serves to address risks throughout the organization, avoiding any potential conflicts of interest. Grifols’ risk management system extends to all companies in the group, including investee firms. Principles of Grifols’ risk control and management system 1. Establishment of a risk tolerance framework, which includes the levels of risk the company deems acceptable and are consistent with its objectives. 2. Leadership from top management, which provides the necessary resources. 3. Integration in management processes, especially those related to strategy and planning. 4. Separation of duties between business areas and supervision and assurance domains. 5. Comprehensive and harmonized management, with all risks managed through a common process of identification, assessment and treatment. 6. Continuous improvement via periodic reviews to ensure the suitability and efficiency of the risk-management system and implementation of best practices and risk-related recommendations.

This model enables observing the different flows of intersectoral transactions in a specific economy in a reference year. In addition, it allows us to observe a series of effects about the production of the system, linked to the final demand, exogenous to it, which appear broken down between the direct or initial, indirect and total effects, which suppose the sum of the previous ones.

For this purpose, the information disclosed includes data from the following territories: Spain, the United States, Ireland, Germany and United Kingdom, as these are the most relevant in terms of business volume and presence within the Grifols Group. The measurement has been performed using data obtained from the information systems based on the criteria of PwC’s Total Tax Contribution (CTT) methodology. In addition to the amounts indicated, there may be other tax payments that have not been taken into account because they are not individually identified in the information systems or are not significant in terms of materiality. TTC methodology The Total Tax Contribution methodology measures the total impact of a company’s tax payments. This assessment is made from the point of view of the total contribution of taxes paid directly to the different public administrations as a result of the Grifols’ Group economic activity carried out. In general, the CTT methodology allocates both input and output taxes to each tax year on a cash basis. The key points to be borne in mind in relation to this methodology are: 1. It distinguishes between taxes that are a cost to Grifols and taxes collected Taxes borne are those taxes that Grifols has paid to the governments of the different countries in which it operates. These taxes are those which have represented an effective cost for Grifols, such as taxes on profits or certain environmental taxes. Taxes collected are the taxes that have been paid as a result of economic activities of Grifols, they are not the own costs of Grifols. Here the company is collecting taxes from others, on behalf of government, i.e. income taxes collected from employees under a payroll system. However, these amounts are paid into the public coffers as a result of the economic activity carried out by Grifols and should therefore be included in the analysis as they represent tax revenue due to the economic value generated by Grifols. 2. TTC Framework classifies taxes under 5 categories for clarification purposes: (i) Profit taxes: includes taxes borne on profits earned by companies such as corporate income tax, business tax and taxes levied as withholding taxes on payments to third parties. (ii) Property taxes: are taxes on the ownership, sale, transfer or occupancy of property. (iii) People (or Employment Taxes): these are employment-related taxes both borne and collected, which include employee income tax withholdings or social security payments payable by both the employee and the Company. (iv) Taxes on Products and Services: take into account indirect taxes on the production and consumption of goods and services, including VAT, customs duties, etc. (v) Planet (Environmental Taxes): taxes on the supply, use or consumption of products and services deemed to affect the environment. 3. It includes all tax payments made to Public Administrations In considering the figures contained in this report, it should be taken into account that they include tax payments made to public administrations for items which, due to their characteristics, are of a tax nature, although for historical or cyclical reasons they are not classified as such. In this way, and in line with the philosophy implemented by the OECD in the analysis of a country’s tax burden, contributions to the different administrations in the form of “social security contributions” have also been included in the above data, as they are a compulsory contribution that generally constitutes a significant part of a State’s income and which, due to its tax configuration rather than its contributory nature, is clearly of a tax nature in Spain. The Mirrlees Report 1, which recommends an integration of taxes on labor income and social insurance where these are of a tax and non-contributory nature, takes a similar view. Likewise, the so-called “Lagares Report” considers Social Security contributions to be taxable in nature, when it includes them in its analysis for the reform of the Spanish tax system, and defines them as “a tax that falls directly on labor, although established with very peculiar criteria, its economic effects are crucial for occupation and employment in the Spanish economy”.

2022 Consolidated Directors’ Report · 196 On the other hand, with regard to the possibility of considering surcharges and interest on late payment as a higher (or lower) contribution, the OECD in its document on the classification as a tax on the various payments to public administrations2, does not expressly refer to interest on late payment and surcharges. In line with this criterion, for the purposes of this report they are not considered as a tax contribution. The same document also clearly indicates how fines and penalties would not be considered as a tax even though they are amounts paid to the Tax Authorities, and therefore should not be considered as a higher contribution. In this sense, we maintain the criterion followed by the OECD, and they are not considered as a higher contribution either. (1) The Mirrlees Report was commissioned by the UK’s IFS and published after four years of work in 2011 under the title “Tax by Design, The Mirrlees Review”. This same report has been studied by experts from the University of Vigo and its conclusions have been included in the document entitled “The Mirrlees Report and Environmental Taxation in Spain”. http://www.ifs. org.uk/mirrleesReview/design (2) https://www.oecd.org/tax/tax-policy/oecd-classification-taxes-interpretative-guide.pdf 4. Profit before taxes assumptions made during the preparation of this report The amount of profit before tax excludes intercompany dividends in order to avoid double-counting of the same income of various entities, if that income was distributed as dividends to the other entities of the Group. Such calculation allows to reflect the objective amount of profit before taxes at country levels, and to calculate the objective ETRs since dividends are usually subject to beneficial tax treatment compared to the other types of income (so-called ‘participation exemption’ regime). 5. There are certain particularities with regard to Value Added Tax and equivalent taxes Value Added Tax (and equivalent taxes) is characterized as a tax on products and services collected, the amount of which reflects the result of the net payments made by Grifols to the tax authorities in each of the jurisdictions in which it operates in the corresponding period. Therefore, considering the mechanics of VAT, the figure indicated for a given country for this concept includes the positive amount paid to the corresponding tax authorities, resulting from subtracting the VAT accrued from the amount of VAT deducted. In case that for the year as a whole and for a country, the net amount resulting from subtracting VAT accrued from VAT deducted is negative as a result of a refund, no figure shall be shown for this item. On the other hand, VAT amounts that are not refundable because the value chain cannot be continued by means of the reverse charge instrument shall be considered as input tax on products and services, as they represent a cost for the Company. In this regard, in the process of preparing the report, we have been informed that some items related to the net VAT position of companies resident in the United States could not be reported for the purposes of computing the TTC, as a result of the difficulty in obtaining them in terms of time and resources.

The SROI method offers Grifols a valuable cost-benefit analysis, offering the leadership team and investors a solid decision-making tool to assess and optimize the firm’s social and environmental impacts. The SROI uses individual assessments to measure the change in stakeholders’ lives because of Grifols’ activities. The evaluations are quantified and recorded on an impact map, and monetary value is then assigned to the resulting social, environmental and economic impacts. 2022 global SROI analysis In 2022, Grifols once again measured the value generated by its U.S. and European donation centers and main plasma medicines as treatment indications for alpha-1 antitrypsin to treat AATD. immunoglobulins for primary immunodeficiencies (PIDD), secondary immunodeficiencies (IDS), chronic inflammatory demyelinating polyneuropathy (CIDP), primary immune thrombocytopenia (ITP), Guillain Barré Syndrome and Myasthenia Gravis (MG). clotting factor VIII. and albumin to treat acute liver disease, hepatorenal syndrome and spontaneous bacterial peritonitis (SBP). Grifols used the SROI (Social Return on Investment) methodology to determine the value generated in 2022 for donors, local communities and patients, and to estimate the global cost-benefit of its treatments.

2022 Consolidated Directors’ Report · 198 Analysis of impact on patients in 2022 In 2022, Grifols remained committed to assessing the impact of its main plasma medicines on patients. A study was conducted by an independent expert using the SROI methodology, focusing specifically on the Plasma Procurement and Biopharma business units’ operations, dedicated to the plasma collection, as well as manufacture and distribution of plasma proteins. During this year, new scientific literature facilitated a better demarcation and assessment of quality of life (QOL) indicators, the most reliable metric to evaluate and quantify patients’ progress. One QALY equals one year in perfect health. If an individual’s health falls below this maximum, QALYs accumulate at a rate of less than one per year. The formula for monetarily calculating the improvement in the patient’s quality of life due to treatment considers the value of living one year in perfect health (1 QALY), weighted by the percentage increase of the patient’s improvement. The following summarizes the different economic valuations used to assess the changes in patients based on the variations experienced in their quality of life (QALY), leveraging the distinct methodologies of two sources: - The Boston-based Institute for Clinical and Economic Review (ICER)1. ICER’s latest value assessment framework states a median value of $100,000 per QALY (with an established lower range value of $50,000 and an upper range value of $150,000). This indicator captures the heterogeneity of patients treated, reflecting a global geographic dispersion. - The proposed by Braithwaite et al.202 gives a QALY value of $297,000 in its high range. This indicator mainly reflects the reality of the US. Euro-dollar exchange rate applied €: 1.0501 USD. It is important to mention that this study was prepared in accordance to the principle of prudence and thus, the impact generated by Grifols is probably greater than that reported in this report. The study was carried out by Mr. Hugo Narrillos Roux - PhD with honors in Economics from the Complutense University of Madrid (Spain) – a specialist in social value, and the author of Economía Social: Valoración y medición de la inversión social (método SROI) (Social Economy: Valuation and Measurement of Social Investment (SROI method)). His thesis was titled, “Social Return on Investment: A Good Method to Measure the Social Value Created by Social Firms.” Mr. Narrillos Roux is recognized as an Accredited SROI practitioner from Social Value International, a member-led network focused on social impact and social value. He teaches at several universities and consults for leading global firms to help them evaluate their social impact. 1. ICER Institute for Clinical and Economic Review website, icer-review. org. 2 .

In total, 22,311 employees have been included in the wage gap calculation, distributed by country as follows: • United States: 16,459 • Spain: 4,138 • Germany: 1,386 • Ireland: 328 The methodology consisted of the use of econometric models that compare the annual salaries at 100% of the occupancy rate of men and women, isolating the effects generated by any and all possible differences identified between the two (socioeconomic factors, job characteristics, etc.). In other words, the adjusted salary gap measures the difference in retribution for the same job or one of equal value and is calculated using the multiple lineal regression model as follows: • For the calculation of the adjusted and unadjusted wage gap, the gross annual fixed salaries of each person at full time have been taken into account. • For the econometric calculation of the adjusted wage gap, the following variables were taken into account: age, seniority, educational level, professional category, contract type, occupancy rate, type of activity, geographical area and performance evaluation. • The results for each country are shown separately, so as not to have to apply a currency exchange rate that distorts the result. • For reasons of confidentiality and protection of personal data, wage gap data are not shown for those professional categories in which there is not a minimum of 3 persons of each sex. • In the case of Ireland, Germany or other small groups, the adjusted wage gap data is not shown because it was not possible to obtain data with sufficient statistical significance using the econometric model. For these cases, only the unadjusted wage gap data is shown.

2022 Consolidated Directors’ Report · 236 Annex XIV: European taxonomy for climate-change mitigation and adaptation The European Sustainable Finance Taxonomy is a new classification of economic activities that contribute to the EU’s environmental objectives, such as mitigating and adapting to climate change, and aims to encourage investments that lead to sustainable growth. To this end, the European Parliament and the Council of the European Union adopted the Taxonomy Regulation1 in 2020. This regulation aims to increase transparency and consistency in the reporting of economic activities that, by meeting specific criteria, can be considered environmentally sustainable. In 2022, as required by Article 8 of the Taxonomy Regulation, Grifols has initiated a process of analysis of its activities in order to identify those which could be considered environmentally sustainable. This process has mainly consisted of two phases: Phase 1. Eligible activities In this first phase, an analysis has been carried out to determine whether or not any of Grifols’ economic activities are considered eligible according to the European taxonomy. Identification of all Grifols’ activities Correlation of their activities with the NACE codes (Nomenclature of Economic Activities). Assessment of the selected NACE codes with the list of eligible activities according to each environmental objective (Annexes I2 and II3). Phase 2. Aligned activities Once the eligible activities had been identified, their suitability for the taxonomy was analysed. For this analysis, the three conditions that an activity must meet in order to be considered environmentally sustainable have been taken into account: Substantial contribution to at least one of the 6 objectives defined by the Taxonomy Principle of do no significant harm to the other defined objectives Principle of do no significant harm to the other defined objectives This process has led to the conclusion that all eligible activities identified in the first phase are aligned with the EU Taxonomy for the environmental objective of Climate Change Mitigation. These are: • 7.4. Installation, maintenance and repair of charging stations for electric vehicles in buildings (and in parking spaces attached to buildings). • 7.6. Installation, maintenance and repair of renewable energy technologies. The proportion of eligible and non-eligible, aligned and non-aligned activities, according to the European taxonomy, is shown below. The organisation’s income is not considered eligible, but some of its investments and expenditures are. After a thorough analysis, these investments and expenses have been considered insignificant in relation to the company’s total, as can be seen in the following tables. The calculation of the main indicators for the identified activities is detailed below. In relation to the taxonomic OpEx, the associated expenses taken into consideration for both activities are composed only of non-capitalized direct costs related to research and development, short-term leases, maintenance and repairs. For both activities, the results have been considered very insignificant. With respect to CapEx, the Group has considered the weight of investments related to the above activity in relation to total additions for the year, whether in Property, Plant and Equipment, software additions, as active capitalized interest. During the 2022 financial year, in terms of CapEx for activity 7.4 Installation, maintenance and repair of charging stations for electric vehicles in buildings (and in the parking spaces attached to the buildings), Grifols has not reported any amount. And with respect to activity 7.6 Installation, maintenance and repair of renewable energy technologies, the result is considered very insignificant. Due to the new information published in reference to the Taxonomy during the year, these results, number of eligible activities and taxonomic KPIs, have undergone variations with respect to those published the previous year.

In the event of discrepancy, the Spanish-language version prevails.) Reg. Mer Madrid, T. 14.972, F. 53, Sec. 8 , H. M -249.480, Inscrip. 1.ª N.I.F. B-82498650 To the Shareholders of Grifols, S.A.: We have been engaged by Grifols, S.A. management to perform a limited assurance review of the accompanying Consolidated Directors’ Report of Grifols, S.A. (hereinafter, the Parent) and subsidiaries (hereinafter, the Group) for the year ended 31 December 2022, prepared with reference to the Sustainability Reporting Standards of the Global Reporting Initiative (GRI Standards) and with the Sustainability Accounting Standards Board (SASB) Standards for Biotechnology & Pharmaceuticals sector (hereinafter, the Report). In addition, pursuant to article 49 of the Spanish Code of Commerce, we have performed a limited assurance review to evaluate whether the Consolidated Non-Financial Information Statement (hereinafter NFIS) of the Group for the year ended 31 December 2022, has been prepared in accordance with prevailing mercantile legislation. The Report includes additional information to that required by GRI Standards, by SASB Standards and prevailing mercantile legislation concerning non-financial information, which has not been the subject of our assurance work. In this respect, our work was limited exclusively to providing assurance on the information contained in the “GRI Content Index”, in the “Appendix I. Table of contents pursuant to Act 11/18 of 28 December on non-financial information and diversity” and in the “SASB Content Index” of the accompanying Report. Responsibility of the Parent’s Directors and Management ___________________ The Directors of the Parent are responsible for the content and authorisation for issue of the NFIS included in the Report. The NFIS has been prepared in accordance with prevailing mercantile legislation and selected GRI Standards based on each subject area in the “Appendix I. Table of contents pursuant to Act 11/18 of 28 December on non-financial information and diversity” table of the aforementioned Report. Management of the Parent is responsible for the preparation and presentation of the Report in accordance with the GRI Standards and SASB Standards for Biotechnology & Pharmaceuticals sector in accordance with each subject area in the tables “GRI Content Index” and “SASB Content Index” of the Report. This responsibility also encompasses the design, implementation and maintenance of internal control deemed necessary to ensure that the Report is free from material misstatement, whether due to fraud or error. The Directors of the Parent are also responsible for defining, implementing, adapting and maintaining the management systems from which the information required to prepare the Report was obtained. (Translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails.) Our Independence and Quality Management _______________________________ We have complied with the independence and other ethical requirements of the International Code of Ethics for Professional Accountants (including international independence standards) issued by the International Ethics Standards Board for Accountants (IESBA), which is founded on fundamental principles of integrity, objectivity, professional competence and due care, confidentiality and professional behaviour. Our firm applies current International Quality Standard and accordingly maintains a comprehensive system of quality control including documented policies and procedures regarding compliance with ethical requirements, professional standards and applicable legal and regulatory requirements. The engagement team was comprised of professionals specialised in reviews of non-financial information and, specifically, in information on economic, social and environmental performance. Our Responsibility ________________________________________________________ Our responsibility is to express our conclusions in an independent limited assurance report based on the work performed. We conducted our review engagement in accordance with the requirements of the Revised International Standard on Assurance Engagements 3000, “Assurance Engagements other than Audits or Reviews of Historical Financial Information” (ISAE 3000 (Revised)), issued by the International Auditing and Assurance Standards Board (IAASB) of the International Federation of Accountants (IFAC), and with the guidelines for assurance engagements on the Non-Financial Information Statement issued by the Spanish Institute of Registered Auditors (ICJCE). The procedures performed in a limited assurance engagement vary in nature and timing from, and are less in extent than for, a reasonable assurance engagement, and consequently, the level of assurance provided is also lower. Our work consisted of making inquiries of management, as well as of the different units and areas of the Group that participated in the preparation of the Report, reviewing the processes for compiling and validating the information presented in the Report and applying certain analytical procedures and sample review tests, which are described below: - Meetings with the Group’s personnel to gain an understanding of the business model, policies and management approaches applied, the principal risks related to these matters and to obtain the information necessary for the external review. - Analysis of the scope, relevance and completeness of the content of the Report based on the materiality analysis performed by the Group and described in the “About this report” section, considering the content required by prevailing mercantile legislation. - Analysis of the processes for compiling and validating the data presented in the Report for 2022. - Review of the information relative to the risks, policies and management approaches applied in relation to the material aspects presented in the Report for 2022. - Corroboration, through sample testing, of the information relative to the content of the Report for 2022 and whether it has been adequately compiled based on data provided by the information sources. - Procurement of a representation letter from the Directors and management.

2022 Consolidated Directors’ Report · 242 GRI 2-5 (Translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails.) Conclusion _______________________________________________________________ Based on the assurance procedures performed and the evidence obtained, nothing has come to our attention that causes us to believe that: a.) The Consolidated Directors’ Report of Grifols, S.A and subsidiaries for the year ended 31 December 2022 has not been prepared, in all material respects, with reference to the GRI Standards and with the SASB Standards for Biotechnology & Pharmaceuticals sector as described in the “GRI content index” and in “SASB content index”, respectively, of the aforementioned Report. b.) The NFIS of Grifols, S.A. and subsidiaries for the year ended 31 December 2022 has not been prepared, in all material respects, in accordance with prevailing mercantile legislation and selected GRI Standards based on each subject area in the “Appendix I. Table of contents pursuant to Act 11/18 of 28 December on non-financial information and diversity” of the Report. Emphasis of Matter _______________________________________________________ Regulation (EU) 2020/852 of the European Parliament and of the Council of 18 June 2020 on the establishment of a framework to facilitate sustainable investment stipulates the obligation to disclose information on how and to what extent the undertaking’s activities are associated with economic activities aligned to the objectives of climate change mitigation and climate change adaptation. This obligation applies for the first time for the 2022 fiscal year, in addition to the information related to eligible activities required in 2021. Consequently, the attached NFIS does not contain comparative information on alignment. Furthermore, as much as the information on eligible activities in 2021 was not required to be as detailed as in 2022, the disclosures on eligibility included in the attached NFIS are not strictly comparable. The directors of Grifols, S.A. have included information on the criteria that, in their opinion, best allow them to comply with the aforementioned obligations, which are defined in annex XIV “European taxonomy for climate change mitigation and adaptation” of the attached Report. Our conclusion is not modified in respect of this matter. Use and Distribution ______________________________________________________ In accordance with the terms of our engagement letter, this Report has been prepared for Grifols, S.A. in relation to its Consolidated Directors’ Report and for no other purpose or in any other context. In relation to the Consolidated NFIS, this report has been prepared in response to the requirement established in prevailing mercantile legislation in Spain, and thus may not be suitable for other purposes and jurisdictions.
