ORDINARY GENERAL SHAREHOLDERS’ MEETING 2021 6 of 72 Proposal regarding Item V on the Agenda: Reduction of share capital through the cancellation of own shares, excluding the right of creditors to object, amending the text of Article 6 of the By-Laws relating to share capital. A) To reduce the share capital of Telefónica, S.A. (“Telefónica” or the “Company”) by the amount of 82,896,466 euros, by means of the cancellation of 82,896,466 own shares of the Company currently held as treasury stock (representing, approximately, 1.5 % of the Company's current share capital). The reduction in share capital will not entail a return of contributions to the shareholders, since the Company itself is the owner of the shares which, where appropriate, will be cancelled and will be made with a charge to unrestricted reserves, by means of the funding of a reserve for cancelled share capital in an amount equal to the par value of the cancelled shares (i.e. in the amount of 82,896,466 euros), which may only be used in compliance with the same requirements as those established for the reduction of share capital, by application of the provisions of section 335. c) of the Companies Act (Ley de Sociedades de Capital). Accordingly, as laid down in such section, the creditors of the Company will not have the right to oppose the reduction mentioned in section 334 of the Companies Act in connection with the approved reduction in share capital. It is hereby stated for the record, in order to comply with the provisions of section 411.1 of the Companies Act, that the consent of the bondholders’ syndicate for the outstanding issues of debentures and bonds is not required, since the approved capital reduction does not reduce the original ratio between the sum of capital plus reserves and the amount of the debentures pending repayment. The capital reduction must be implemented within one year from the adoption of this resolution. B) To authorize the Board of Directors so that, within a period of one year from the adoption of this resolution, it may determine those points that have not been expressly established in this resolution or that are a result thereof, and to adopt the resolutions, take the actions and execute the public or private documents that may be necessary or appropriate for the full execution of the agreed share capital reduction, including, by way of example, the publication of the legally required notices and the making of the appropriate applications and the giving of the appropriate notices to delist the cancelled shares from the stock exchange. The delegation includes the power to redraft article 6 of the By-Laws, relating to share capital. The Board of Directors is expressly authorized to in turn delegate to the Executive Commission or the Executive Chairman of the Board of Directors, the powers referred in this resolution, without prejudice to the powers that may be granted to any person for specific acts of execution. * * *

Telefónica, S.A. ORDINARY GENERAL SHAREHOLDERS’ MEETING 2021 7 of 72 Proposal regarding Item VI on the Agenda: Shareholder compensation via scrip dividends. VI.1.- First scrip dividend resolution. Approval of an increase in share capital with a charge to reserves by such amount as may be determined pursuant to the terms and conditions of the resolution, through the issuance of new ordinary shares having a par value of one euro each, and with a provision for incomplete allocation. Offer to the shareholders to purchase their free allotment rights at a guaranteed price. 1.- Capital increase with a charge to reserves Approval of an increase in share capital in the amount resulting from multiplying (a) the par value of one euro per share of Telefónica, S.A. (“Telefónica” or the “Company”) by (b) the number of new shares of the Company to be determined using the formula indicated under section 2 below. The capital increase will be carried out by means of the issuance and flotation of new ordinary shares, having a par value of one euro each, of the same class and series as those that are currently outstanding, represented by book entries. The capital increase will be carried out in its entirety with a charge to one of the reserves provided for in section 303.1 of the Companies Act (Ley de Sociedades de Capital). The new shares will be issued at par, i.e., at their nominal value of one euro, without a share premium, and will be allotted without charge to those shareholders who exercise their free allotment rights. Pursuant to the provisions of section 311 of the Companies Act, provision is made for the possibility of an incomplete allotment of the capital increase in the event that the Company, a company within its Group or a third party waives part or all of the free allotment rights to which they are entitled at the time of implementation of the increase. In the event of such incomplete allotment, the share capital will be increased by the corresponding amount. 2.- New shares to be issued The maximum number of new shares to be issued will be the number resulting from the application of the following formula, rounded down to the nearest whole number: NNS = TNShrs / Number of rights Where: “NNS” is the maximum number of new shares to be issued; “TNShrs” is the number of shares of the Company on the date it is resolved to implement the capital increase; and “Number of rights” is the number of free allotment rights required for the allotment of one new share, which will be the number resulting from applying the following formula, rounded up to the nearest whole number:

Telefónica, S.A. ORDINARY GENERAL SHAREHOLDERS’ MEETING 2021 8 of 72 Number of rights = [TNShrs x ListPri] / Reference Amount Where: “Reference Amount” will be the market reference value of the capital increase, which will be the result of applying the following formula: Reference Amount = TNShrs x 0.20 x ListPri / (ListPri - 0.20), which may not exceed the sum of 1,250,000,000 euros. “ListPri” is the arithmetic mean of the average weighted prices of the shares of the Company on the Spanish Automated Quotation System (Sistema de Interconexión Bursátil Español) during the 5 trading sessions closed prior to the resolution of the Board of Directors to carry out the capital increase, rounded to the nearest one-thousandth of a euro and, in the case of one-half of one-thousandth of a euro, rounded up to the nearest one- thousandth. In any case, ListPri may not be less than the par value of the shares of Telefónica, such that if the result of such calculation is less, ListPri will be equal to one euro. The maximum number of new shares to be issued thus calculated will be subject to the corresponding rounding to obtain a whole number of shares (by rounding the result down to the nearest whole number) and a rights-to-shares conversion ratio that is also whole (by rounding the result up to the nearest whole number). Additionally, and for the same purposes, the Company (or any entity within its group that holds shares of the Company) will waive the free allotment rights corresponding thereto as provided in section 3 below. 3.- Free allotment rights Each share of the Company will grant one free allotment right. The number of free allotment rights required to receive one new share will be automatically determined according to the ratio existing between the maximum number of shares to be issued (NNS) and the number of shares of the Company at the date it is resolved to carry out the capital increase (TNShrs), calculated in accordance with the formula set forth in section 2 above. Specifically, the shareholders will be entitled to receive one new share for in the corresponding proportion for as many free allotment rights, determined as provided in section 2 above (Number of rights), as they hold. In the event that the number of free allotment rights required for the allotment of one new share (Number of rights) multiplied by the maximum number of new shares to be issued (NNS) results in a number that is lower than the number of shares of the Company on the date it is resolved to carry out the capital increase (TNShrs), the Company (or any entity within its Group that holds shares of the Company) will waive a number of free allotment rights equal to the difference between both figures, solely for the purpose of the number of new shares being a whole number and not a fraction. The free allotment rights will be allotted to the shareholders who appear as being entitled thereto in the book-entry records of Sociedad de Gestión de los Sistemas de Registro, Compensación y Liquidación de Valores, S.A.U. (IBERCLEAR) on the relevant date in

Telefónica, S.A. ORDINARY GENERAL SHAREHOLDERS’ MEETING 2021 9 of 72 accordance with applicable rules governing the clearing and settlement of securities. The free allotment rights will be transferable on the same conditions as the shares from which they derive. The free allotment rights may be traded on the Spanish continuous market during the term determined by the Board of Directors, subject to a minimum of fifteen calendar days (unless the applicable regulations provide for a different minimum period, in which case the period determined by the Board of Directors may not be less than such minimum period). Sufficient free allotment rights in the proportion required to subscribe for new shares may be acquired on the market during said trading period. Once the period for trading the free allotment rights has ended, the new shares that it has not been possible to allot will be held on deposit for those who provide evidence that they are the lawful holders of the corresponding free allotment rights. Upon the passage of three years from the end of the aforementioned period for trading the free allotment rights, the new shares that are still pending allotment may be sold, for the account and risk of the interested parties, in accordance with the provisions of section 117 of the Companies Act. The net proceeds from such sale will be kept available for the interested parties as provided for by applicable law. 4.- Irrevocable undertaking to purchase the free allotment rights The Company, or such company of its group as may be determined, will assume an irrevocable undertaking to purchase the free allotment rights at the price set forth below, exclusively in favor of the shareholders who were originally allotted the rights and solely in relation to the initially allotted rights, and the purchase undertaking may not be enforced with respect to free allotment rights that are acquired on or outside of the market. The purchase undertaking will be effective during such term as is established by the Board of Directors, within the period for trading the rights. For such purpose, the Company, or the corresponding company of its group, is authorized to acquire such free allotment rights (as well as the shares corresponding thereto) up to the maximum limit of the total number of rights issued, subject to compliance with legal limitations in all cases. The purchase price of each free allotment right under the purchase undertaking (Purchase Price) will be equal to the amount resulting from the following formula, rounded to the nearest one-thousandth of a euro, and in the case of one-half of one-thousandth of a euro, rounded up to the nearest one-thousandth of a euro: Purchase Price = ListPri / (Number of rights + 1) By decision of the Board of Directors, the Company may acquire the free allotment rights as a result of the purchase undertaking in part or in full, with a charge to results for the fiscal year or one of the reserves provided for in section 303.1 of the Companies Act. Provision is made for the Company to waive the exercise of the free allotment rights acquired pursuant to the aforementioned purchase undertaking, such that the share capital will be increased only by the amount corresponding to the free allotment rights that have not been waived.

ORDINARY GENERAL SHAREHOLDERS’ MEETING 2021 40 of 72 Shareholders’ Meeting, either by using the proxy form printed on the attendance card or in any other manner permitted by the law, without prejudice to the provisions of the Companies Act (Ley de Sociedades de Capital) regarding cases of proxies granted to family relatives and general proxies. The documents setting forth the proxies for the General Shareholders’ Meeting shall contain instructions regarding the direction of the vote. Unless otherwise expressly indicated by the shareholder granting the proxy, it shall be understood that the shareholder gives specific instructions to vote in favor of the proposed resolutions put forward by the Board of Directors regarding the matters on the agenda. If there are no voting instructions because the shareholders acting at the General Shareholders’ Meeting are to decide matters that are not included in the agenda and are thus unknown on the date that the proxy is granted but which may be submitted to a vote at the General Shareholders’ Meeting, the proxy-holder shall vote in such direction as he deems most appropriate, taking into account the interest of the Company and that of the shareholder granting the proxy. The same rule shall apply when the relevant proposal or proposals submitted to the shareholders at the General Shareholders’ Meeting have not been made by the Board of Directors. If the document setting forth the proxy does not state the specific person or persons to whom the shareholder grants the proxy, such proxy shall be deemed granted in favor of any of the following: the Chairman of the Board of Directors of the Company, or the person that stands in for him as Chairman of the General Shareholders’ Meeting, or such person as is appointed by the Board of Directors, with notice of such appointment being given in advance in the notice of the call to meeting. If the Chairman of the Board of Directors of the Company, or the person acting in his stead, or the person appointed by the Board of Directors, as applicable, is affected by any of the conflicts of interest contemplated in the law and the document setting forth the proxy does not contain any specific instructions, the proxy shall be deemed granted to the Secretary for the General Shareholders’ Meeting. A proxy is always revocable. Casting the vote remotely and attendance at the General Shareholders’ Meeting by the shareholder granting the proxy entails the revocation of any proxy granted, whatever the date thereof. A proxy shall likewise be rendered void as a result of the disposition of shares of which the Company has notice. 2. Individual shareholders who do not have full legal capacity and corporate shareholders shall be represented by those persons who act as representatives thereof pursuant to law, with evidence of such representative capacity being duly provided. 3.

By way of exception, institutions that are

ORDINARY GENERAL SHAREHOLDERS’ MEETING 2021 41 of 72 duly registered as shareholders according to the book-entry share register but that act for the account of several persons may, without limitation, delegate the right to vote to each of the indirect holders or to third parties designated by such indirect holders. In addition, such institutions may in all cases split their vote and exercise the right to vote in a different direction in compliance with differing voting instructions that they have received. 4. The Chairman of the General Shareholders’ Meeting or, by delegation of powers, the Secretary of the General Shareholders’ Meeting shall resolve all doubts regarding the validity and effectiveness of the documents giving rise to the right of any shareholder to attend the General Shareholders’ Meeting, whether individually or by grouping their shares with other shareholders, as well as any proxy granted to any other person, endeavoring to deem only those documents that lack the minimum essential requirements to be invalid or ineffective, provided that such defects have not been remedied. 5. When a proxy is granted by means of long-distance communication, it shall only be deemed valid if it is granted by postal delivery or correspondence or by electronic communication made in accordance with the provisions of this section. Proxies by postal delivery or correspondence shall be granted by sending or delivering to the Company the duly signed attendance and proxy-granting card or other written instrument that, in the opinion of the Board of Directors expressed in a resolution adopted for such purpose, allows for due verification of the identity of the shareholder granting the proxy and that of the proxy-holder designated therein. Proxies by electronic communication to the Company shall be granted under an electronic signature or by such other manner as the Board of Directors may deem appropriate to ensure the authenticity and identification of the shareholder that exercises his right, attaching thereto a copy in electronic format of the attendance and proxy-granting card and detailing in the communication the proxy granted and the identity of the shareholder granting the proxy. In order to be valid, a proxy granted by either of the aforementioned means of long-distance communication must be received by the Company before midnight on the third day prior to the date set for the holding of the General Shareholders’ Meeting upon first call. In the resolution for the call of the General Shareholders’ Meeting in question, the Board of Directors may reduce this required deadline, disclosing it in the same manner as the call notice. The Board of Directors may also implement the above provisions relating to proxies granted by long-distance means of communication in accordance with the provisions of Article 25.5 of the By-Laws and Article 22.7 of these Regulations. 6. A proxy may include items that, even if not contained in the agenda, may be dealt with by the shareholders at the General Shareholders’ Meeting because it is so permitted by law.

The Board of Directors is authorized to implement and supplement the regulations on voting and granting of proxies by long-distance means of communication provided for in these Regulations, establishing the instructions, means, rules and procedures it deems appropriate to instrument the casting of votes and the grant of proxies by long-distance means of communication. In any event, the Board of Directors will adopt the necessary measures to avoid possible duplications and to ensure that the person who has cast the vote or granted the proxy by means of postal or electronic correspondence has the proper standing to do so in accordance with the provisions of Article 19.1 of the By-laws. The implementing rules adopted by the board of Directors pursuant to the provisions of this subarticle shall be published on the corporate website.” g) To amend article 23 of the Regulations for the General Shareholders’ Meeting, which shall henceforth read as follows: “Article 23. Voting on the proposed resolutions. 1. Once shareholders’ presentations, if any, have concluded and answers have been provided as set forth in these Regulations, the corresponding proposed resolutions shall be put to the vote. Each of the proposed resolutions shall be voted by following the agenda included in the notice of the call to meeting, and if proposals have been made regarding matters which the shareholders may decide without such matters being included in the agenda, they shall be submitted to a vote after a vote is taken on the proposals included in the agenda, unless the Chairman of the General Shareholders’ Meeting decides otherwise. 2. After the Secretary for the General Shareholders’ Meeting has read the full text or a summary of the proposed resolution corresponding to an item on the agenda, which reading may be dispensed with when the text of such proposal has been distributed to the shareholders at the beginning of the General Shareholders’ Meeting, a vote shall first be taken on the resolutions proposed in each case by the Board of Directors, and then, if appropriate, the proposals made by other parties shall be submitted to a vote, following the order established by the Chairman of the General Shareholders’ Meeting for that purpose. When a single item on the Agenda includes different matters, such matters shall be separately submitted to a vote. In particular, a separate vote shall

Telefónica, S.A. ORDINARY GENERAL SHAREHOLDERS’ MEETING 2021 46 of 72 be taken on the appointment, ratification, re-election or removal of each Director and, in the event of amendments to the By-Laws or these Regulations, on each article or group of articles that are materially independent. In exceptional cases, related proposals, which are formulated as an indivisible unit, shall be voted as a whole, such as those relating to the approval of the revised text of the By-Laws or of the Regulations for the General Shareholders’ Meeting. In all cases, when a proposed resolution is approved, all other proposals on the same matter that are incompatible therewith shall automatically be deemed withdrawn and shall therefore not be submitted to a vote, which shall be stated by the Chairman of the General Shareholders’ Meeting, or by the Secretary for the General Shareholders’ Meeting, acting by delegation of powers. 3. The following voting calculation system shall be used for purposes of voting on the proposed resolutions: a) In the case of voting on proposed resolutions relating to matters on the agenda, votes in favor of the proposal submitted to a vote shall be deemed to be those corresponding to all shares present or represented at the Meeting, according to the attendance roll, less the votes corresponding to shares whose holders or representatives inform the Presiding Committee of the General Shareholders’ Meeting, or to the Notary, if appropriate, by written or electronic communication, or personal statement, that they vote against, in blank or abstain. b) In the case of voting on proposed resolutions relating to matters that are not included in the agenda, votes against the proposal submitted to a vote shall be deemed to be those corresponding to all shares present or represented at the Meeting, according to the attendance roll, less the votes corresponding to shares whose holders or representatives inform the Presiding Committee of the General Shareholders’ Meeting, or to the Notary, if appropriate, by written or electronic communication, or personal statement, that they vote in favor, in blank or abstain. c) For purposes of the provisions of paragraphs a) and b) above, for each of the proposed resolutions submitted to a vote, it shall be deemed that shares present and represented at the meeting are all those recorded on the attendance roll, less the shares whose holders may not, pursuant to the law and depending upon the proposed resolution that is put to the vote, exercise the voting rights attaching to their shares. Regardless of the system used to calculate the votes, verification by the Presiding Committee of the Meeting – or, exceptionally, in the event that such Presiding Committee of the General Shareholders’ Meeting has not been formed, by the Secretary for the General Shareholders’ Meeting – of the existence of a number of favorable votes sufficient to attain the majority required in each case, will allow the Chairman of the General Shareholders’ Meeting to declare the relevant proposed resolution to have been approved.”

Telefónica, S.A. ORDINARY GENERAL SHAREHOLDERS’ MEETING 2021 47 of 72 VIII.2 Amendment of the Regulations for the General Shareholders’ Meeting to expressly regulate the possibility of granting proxies and casting votes prior to the General Shareholders’ Meeting by telephone: articles 13 (Right of representation) and 22 (Casting of votes from a distance prior to the General Shareholders’ Meeting). Incorporate in articles 13 (Right of representation) and 22 (Casting of votes from a distance prior to the General Shareholders’ Meeting) of the Regulations for the General Shareholders’ Meeting the following amendments: a) To amend article 13 of the Regulations for the General Shareholders’ Meeting, which shall henceforth read as follows (without prejudice to the proposal made under item VIII.1 to enable the General Shareholders' Meeting to be held exclusively by telematic means): “Article 13. Right of representation. 1. Every shareholder having the right to attend the General Shareholders’ Meeting may be represented thereat by another person, even if not a shareholder, provided that the requirements and formalities imposed by the law are met. The proxy must be granted specifically for each General Shareholders’ Meeting, either by using the proxy form printed on the attendance card or in any other manner permitted by the law, without prejudice to the provisions of the Companies Act (Ley de Sociedades de Capital) regarding cases of proxies granted to family relatives and general proxies. The documents setting forth the proxies for the General Shareholders’ Meeting shall contain instructions regarding the direction of the vote. Unless otherwise expressly indicated by the shareholder granting the proxy, it shall be understood that the shareholder gives specific instructions to vote in favor of the proposed resolutions put forward by the Board of Directors regarding the matters on the agenda. If there are no voting instructions because the shareholders acting at the General Shareholders’ Meeting are to decide matters that are not included in the agenda and are thus unknown on the date that the proxy is granted but which may be submitted to a vote at the General Shareholders’ Meeting, the proxy-holder shall vote in such direction as he deems most appropriate, taking into account the interest of the Company and that of the shareholder granting the proxy. The same rule shall apply when the relevant proposal or proposals submitted to the shareholders at the General Shareholders’ Meeting have not been made by the Board of Directors. If the document setting forth the proxy does not state the specific person or persons to whom the shareholder grants the proxy, such proxy shall be deemed granted in favor of any of the following: the Chairman of the Board of Directors of the Company, or the person that stands in for him as Chairman of the General Shareholders’ Meeting, or such person as is appointed by the Board of Directors, with notice of such appointment being given in advance

Telefónica, S.A. ORDINARY GENERAL SHAREHOLDERS’ MEETING 2021 48 of 72 in the notice of the call to meeting. If the Chairman of the Board of Directors of the Company, or the person acting in his stead, or the person appointed by the Board of Directors, as applicable, is affected by any of the conflicts of interest contemplated in the law and the document setting forth the proxy does not contain any specific instructions, the proxy shall be deemed granted to the Secretary for the General Shareholders’ Meeting. A proxy is always revocable. Attendance at the General Shareholders’ Meeting by the shareholder granting the proxy, whether in person or through distance voting, entails the revocation of any proxy granted, whatever the date thereof. A proxy shall likewise be rendered void as a result of the disposition of shares of which the Company has notice. 2. Individual shareholders who do not have full legal capacity and corporate shareholders shall be represented by those persons who act as representatives thereof pursuant to law, with evidence of such representative capacity being duly provided. 3. Both in cases of voluntary representation as well as those of legal representation, no person may have more than one representative at the General Shareholders’ Meeting. By way of exception, institutions that are duly registered as shareholders according to the book-entry share register but that act for the account of several persons may, without limitation, delegate the right to vote to each of the indirect holders or to third parties designated by such indirect holders. In addition, such institutions may in all cases split their vote and exercise the right to vote in a different direction in compliance with differing voting instructions that they have received. 4. The Chairman of the General Shareholders’ Meeting or, by delegation of powers, the Secretary of the General Shareholders’ Meeting shall resolve all doubts regarding the validity and effectiveness of the documents giving rise to the right of any shareholder to attend the General Shareholders’ Meeting, whether individually or by grouping their shares with other shareholders, as well as any proxy granted to any other person, endeavoring to deem only those documents that lack the minimum essential requirements to be invalid or ineffective, provided that such defects have not been remedied. 5. When a proxy is granted by means of long-distance communication, it shall only be deemed valid if it is granted by postal delivery or correspondence or by electronic communication made in accordance with the provisions of this section. Proxies granted by telephone in accordance with the procedure, where applicable, set forth in the call notice shall be deemed to have been granted by electronic communication. Proxies by postal delivery or correspondence shall be granted by sending or delivering to the Company the duly signed attendance and proxy-granting card or other written instrument that, in the opinion of the Board of Directors expressed in a resolution adopted for such purpose, allows for due verification of the identity of the shareholder granting the proxy and that of the proxy-holder designated therein.

Telefónica, S.A. ORDINARY GENERAL SHAREHOLDERS’ MEETING 2021 49 of 72 Proxies by electronic communication to the Company shall be granted under an electronic signature or by such other manner as the Board of Directors may deem appropriate to ensure the authenticity and identification of the shareholder that exercises his right, and, where granted by electronic means, attaching thereto a copy in electronic format of the duly completed attendance and proxy-granting card. In order to be valid, a proxy granted by either of the aforementioned means of long-distance communication must be received by the Company before midnight on the third day prior to the date set for the holding of the General Shareholders’ Meeting upon first call. In the resolution for the call of the General Shareholders’ Meeting in question, the Board of Directors may reduce this required deadline, disclosing it in the same manner as the call notice. The Board of Directors may also implement the above provisions relating to proxies granted by long-distance means of communication in accordance with the provisions of Article 25.5 of the By-Laws and Article 22.7 of these Regulations. 6. A proxy may include items that, even if not contained in the agenda, may be dealt with by the shareholders at the General Shareholders’ Meeting because it is so permitted by law.” b) To amend article 22 of the Regulations for the General Shareholders’ Meeting, which shall henceforth read as follows (without prejudice to the proposal made under item VIII.1 to enable the General Shareholders' Meeting to be held exclusively by telematic means): “Article 22. Casting of votes from a distance prior to the General Shareholders’ Meeting. 1. Without prejudice to the provisions of Article 18 of these Regulations, and therefore, independently of the right to attend by electronic means, shareholders with the right to attend may cast their vote on the proposals relating to the items included in the Agenda for any General Shareholders' Meeting by means of postal delivery or correspondence or electronic communication. Votes cast by telephone in accordance with the procedure, where applicable, set forth in the call notice shall be deemed to have been cast by electronic communication. 2. Votes by postal delivery or correspondence shall be cast by sending or delivering to the Company a document recording the vote accompanied by the duly signed attendance card issued by the entity in charge of keeping the register of book entries. 3. Votes communicated electronically to the Company shall be cast under an electronic signature or in such other manner as the Board of Directors may deem appropriate to ensure the authenticity and the identification of the shareholder exercising his right, and, if cast through electronic means, attaching thereto a copy in electronic format of the duly completed attendance card and vote.

Shareholders who cast their vote from a distance pursuant to this article and to the provisions made by the Board of Directors by way of further development thereof shall be deemed present for purposes of determining the establishment of a quorum for the General Shareholders' Meeting in question. Therefore, proxies granted prior to the casting of such vote shall be deemed revoked, and those granted thereafter shall be deemed not to have been given. 6. The vote cast by means of long-distance communication shall be rendered void by the attendance in person at the meeting of the shareholder casting the vote or by the disposition of shares of which the Company has notice. 7. The Board of Directors is authorized to implement and supplement the regulations on voting and granting of proxies by long-distance means of communication provided for in these Regulations, establishing the instructions, means, rules and procedures it deems appropriate to instrument the casting of votes and the grant of proxies by long-distance means of communication. In any event, the Board of Directors will adopt the necessary measures to avoid possible duplications and to ensure that the person who has cast the vote or granted the proxy by means of postal or electronic correspondence has the proper standing to do so in accordance with the provisions of Article 19.1 of the By-laws. The implementing rules adopted by the board of Directors pursuant to the provisions of this subarticle shall be published on the corporate website.”

In all cases, when a proposed resolution is approved, all other proposals on the same matter that are incompatible therewith shall automatically be deemed withdrawn and shall therefore not be submitted to a vote, which shall be stated by the Chairman of the General Shareholders’ Meeting, or by the Secretary for the General Shareholders’ Meeting, acting by delegation of powers. 3. The following voting calculation system shall be used for purposes of voting on the proposed resolutions: a) In the case of voting on proposed resolutions relating to matters on the agenda, votes in favor of the proposal submitted to a vote shall be deemed to be those corresponding to all shares present or represented at the Meeting, according to the attendance roll, less the votes corresponding to shares whose holders or representatives inform the Presiding Committee of the General Shareholders’ Meeting, or to the Notary, if appropriate, by written or electronic communication, or personal statement, that they vote against, in blank or abstain. b) In the case of voting on proposed resolutions relating to matters that are not included in the agenda, votes against the proposal submitted to a vote shall be deemed to be those corresponding to all shares present or represented at the Meeting, according to the attendance roll, less the votes corresponding to shares whose holders or representatives inform the Presiding Committee of the General Shareholders’ Meeting, or to the Notary, if appropriate, by written or electronic communication, or personal statement, that they vote in favor, in blank or abstain. c) For purposes of the provisions of paragraphs a) and b) above, for each of the proposed resolutions submitted to a vote, it shall be deemed that shares present and represented at the meeting are all those recorded on the attendance roll, less the shares whose holders may not, pursuant to the law and depending upon the proposed resolution that is put to the vote, exercise the voting rights attaching to their shares. Regardless of the system used to calculate the votes, verification by the Presiding Committee of the Meeting – or, exceptionally, in the event that such Presiding Committee of the General Shareholders’ Meeting has not been formed, by the Secretary for the General Shareholders’ Meeting – of the existence of a number of favorable votes sufficient to attain the majority

Telefónica, S.A. ORDINARY GENERAL SHAREHOLDERS’ MEETING 2021 63 of 72 January 1, 2022 (with delivery of the respective shares in 2025, once the financial statements for fiscal year 2024 have been prepared and audited) and the third shall commence on January 1, 2023 (with delivery of the respective shares in 2026, once the financial statements for fiscal year 2025 have been prepared and audited). 5.- Maximum number of shares of Telefónica, S.A. included in the Plan: the maximum total number of shares of Telefónica, S.A. that are to be delivered to the Participants at the end of each of the cycles in implementation of the Plan shall be the result of dividing the maximum amount allocated to each cycle by the average weighted listing price of the shares of Telefónica, S.A. in the thirty trading days prior to January 1 of the first year of the corresponding cycle (hereinafter, the “Reference Value”). The maximum total amount allocated to the Plan is set at two hundred million euros (€ 200,000,000). The maximum amount allocated to each of the cycles of the Plan shall be determined annually by the Board of Directors upon a prior report from the Nominating, Compensation and Corporate Governance Committee, and may not exceed the aforementioned overall figure of two hundred million euros (€ 200,000,000) for the three cycles of the Plan. The amounts committed but not ultimately used in each cycle (due to non-achievement of objectives, withdrawals, etc.) shall be available for subsequent cycles. In any event, the total shares to be delivered in implementation of the Plan to all of the Participants (including Executive Directors) at the end of each cycle can never exceed 0.45% of the share capital of Telefónica, S.A. at the commencement of the respective cycle. In particular, if 100% of the Plan objectives (economic/financial, creation of value for the shareholders, and linked to sustainability, the environment and good governance) were met, the Executive Directors of Telefónica, S.A. would have the right, at the end of each of the three cycles, to receive a maximum number of shares whose value is equivalent to 250% of their Annual Fixed Remuneration for the first year of the respective cycle. For the first cycle of the Plan, taking into consideration the average weighted listing price of the shares of Telefónica, S.A. in the thirty (30) trading days prior to January 1, 2021 and the Annual Fixed Remuneration of the Executive Directors for 2021, such maximum number of shares if 100% of the Plan objectives are met is equivalent to one million three hundred sixty-seven thousand eighty-one (1,367,081) shares for the Executive Chairman, Mr. José María Álvarez-Pallete López, and to one million one hundred thirty-seven thousand three hundred ninety- eight (1,137,398) shares for the Chief Operating Officer, Mr. Ángel Vilá Boix. In any event, the number of shares to be delivered shall depend on the allocation approved by the Board of Directors and on the level of achievement of the objectives of the Plan.

Telefónica, S.A. ORDINARY GENERAL SHAREHOLDERS’ MEETING 2021 64 of 72 For each of the remaining cycles and upon a prior report from the Nominating, Compensation and Corporate Governance Committee, the Board of Directors shall determine the maximum amounts that will be used as a basis to set the maximum number of shares that can be delivered based on the respective Reference Value. In no case may such maximum amount exceed 250% of the Annual Fixed Remuneration of each of the Executive Directors of Telefónica, S.A. who are beneficiaries of the Plan for either of the two remaining cycles of the Plan. The number of shares effectively delivered to each Executive Director at the end of each cycle in implementation of this Plan, as well as the number of shares effectively delivered to the other Senior Executive Officers of the Telefónica Group, shall be disclosed in accordance with the provisions of applicable law. 6.- Requirements and conditions for delivery of shares: the specific number of shares of Telefónica, S.A. that will be delivered to the Participants at the end of each cycle, within the established limit, shall be subject to and determined by the achievement of economic/financial objectives consisting of the creation of shareholder value, as well as objectives linked to sustainability, the environment and corporate governance. The objectives shall be approved by the Board of Directors at the beginning of each cycle of the Plan, upon a proposal of the Nominating, Compensation and Corporate Governance Committee, within the framework established in the Directors’ Remuneration Policy, which is submitted for the approval of this Shareholders’ Meeting under item IX on the Agenda. Each Participant shall be allotted a maximum number of theoretical shares at the commencement of the respective cycle. The specific number of shares to be delivered shall depend on the level of achievement of the objectives set for each cycle. In the first cycle of the Plan, subject to the approval of this resolution by the Shareholders’ Meeting and the adoption of the corresponding resolutions by the Board of Directors and by the Nominating, Compensation and Corporate Governance Committee, the number of shares to be delivered shall depend (i) 50% on achievement of the total shareholder return (hereinafter, as defined below, the “TSR”) objective for shares of Telefónica, S.A., (ii) 40% on the generation of free cash flow of the Telefónica Group (the “FCF”), and (iii) 10% on CO2 Emission Neutralization, in line with the goal set by the company to reach zero net emissions by 2025. TSR is considered the metric to determine the generation of medium-term and long-term value in the Telefónica Group, as it measures the return on the shareholder’s investment, and is defined, for such purposes, as the profitability of the share having regard to the accumulated change in the listing value of the Telefónica, S.A. share and the dividends and other similar items received by the shareholder during the first cycle of the Plan. To determine achievement of the TSR objective and calculate the specific number of shares to be delivered for this item, the TSR of Telefónica, S.A. shares during the first cycle of the Plan shall be measured in comparison to the TSRs reached by certain companies belonging to the telecommunications sector, weighted

Telefónica, S.A. ORDINARY GENERAL SHAREHOLDERS’ MEETING 2021 65 of 72 according to their relevance for Telefónica, S.A., which shall constitute the comparison group for purposes of the Plan (hereinafter, the “Comparison Group”). The companies included in the Comparison Group for the first cycle of the Plan, for purposes of comparing the evolution of the TSR of Telefónica, S.A. shares, are listed below: Vodafone Group America Movil Deutsche Telekom BT Group Orange Telecom Italia Telenor TeliaSonera Swisscom Koninklijke KPN TIM Brasil Proximus Millicom Liberty Global Altice Europe For subsequent cycles of the Plan and upon a prior report from the Nominating, Compensation and Corporate Governance Committee, the Board of Directors of Telefónica, S.A. may update the list of the companies included in the Comparison Group and determine their weighting, maintaining the economic foundations of the Plan. In relation to achievement of the TSR objective, the Plan shall provide that the number of shares to be delivered tied to the achievement of this objective will vary between 15% of the allotted number of theoretical shares, where the performance of the TSR of Telefónica, S.A. shares is at least at the median of the Comparison Group (with the incentive not being paid below this threshold), and 50% where such performance is at the third quartile or higher of the Comparison Group, the percentage to be calculated by interpolation in those cases falling between the median and the third quartile. To determine achievement of the FCF objective and calculate the specific number of shares to be delivered for this item, the level of FCF generated by the Telefónica Group in each year shall be measured and compared to the value set in the budgets approved by the Board of Directors for each fiscal year, considering the level of final achievement of FCF to be the average of the partial annual results obtained and approved by the Nominating, Compensation and Corporate Governance Committee. At the beginning of each cycle, the Board of Directors, upon a proposal of the Nominating, Compensation and Corporate Governance Committee, shall determine an achievement scale that will include a minimum threshold of 90%

Telefónica, S.A. ORDINARY GENERAL SHAREHOLDERS’ MEETING 2021 66 of 72 achievement, below which no incentive will be paid, and the achievement of which will entail the delivery of 20% of the allotted theoretical shares, and a maximum level of 100% achievement, which will entail the delivery of 40% of the allotted theoretical shares. In order to determine achievement of the CO2 Emissions Neutralization objective and calculate the specific number of shares to be delivered for this item, the level of CO2 emissions neutralization achieved at the end of the cycle will be measured, it also being necessary to achieve a particular level of reduction in scope 1 + 2 emissions, in line with the 1.5ºC scenario of the Paris Agreement (SBTi) and with the Company’s objective of net zero emissions by 2025 in its 4 core markets for scopes 1 + 2 Emission neutralization is the purchase of carbon credits to absorb CO2 from the atmosphere. To become a net zero emissions company, emissions of CO2 (scopes 1 + 2) must be reduced in line with the 1.5ºC scenario, and all remaining emissions (i.e., those that could not be avoided) must be neutralized. Carbon credits consist of the purchase of CO2 certificates on the voluntary market. These credits are generated by projects that absorb CO2 from the atmosphere; the projects must have the highest international quality certifications and must also entail social benefits to the greatest extent possible. This information is verified annually by an external auditor. Scope 1 and 2 emissions consist of direct and indirect CO2 emissions from our daily activity due to fuel consumption, refrigerant gas leaks and electricity use. Net emissions are calculated as the difference between scope 1+2 emissions and the purchase of carbon credits. The level of direct and indirect CO2 emissions from our daily activity shall be calculated as follows: CO2 Emission = Activity x Emission Factor Where: - Activity: Amount of energy, fuel, gas, etc. consumed by the Company. - Emission Factor: Amount of CO2 that is emitted into the atmosphere by the consumption of each unit of activity. The emission factor provided by official sources (European Union, Ministries, CNMC, etc.) is used for electricity and the emission factors of the GHG Protocol are used for fuel. At the beginning of the cycle, the Board of Directors, upon a proposal of the Nominating, Compensation and Corporate Governance Committee, shall determine an achievement scale that will include a minimum threshold of 90% achievement, below which no incentive will be paid, and the achievement of which

Telefónica, S.A. ORDINARY GENERAL SHAREHOLDERS’ MEETING 2021 67 of 72 will entail the delivery of 5% of the allotted theoretical shares, and a maximum level of 100% achievement, which will entail the delivery of 10% of the allotted theoretical shares. In addition, a minimum level of reduction of scope 1 + 2 emissions in line with the 1.5ºC scenario of the Paris Agreement (SBTi) must be achieved for this part of the incentive to be paid. The Nominating, Compensation and Corporate Governance Committee will conduct an annual review of the objectives, and the level of achievement will be determined upon completion of each Plan cycle. For this evaluation work, the Nominating, Compensation and Corporate Governance Committee shall have the support of the Audit and Control Committee, which will provide information regarding the results audited by the external auditor and the Company’s internal auditor, which shall be first analyzed by the Audit and Control Committee itself. The Nominating, Compensation and Corporate Governance Committee shall also take into account any associated risk in establishing objectives and evaluating achievement thereof. Positive or negative financial effects arising out of extraordinary events that may cause distortions in the results of the evaluation shall be eliminated when determining the level of achievement of the objectives, and the quality of the results over the long term shall be considered in the proposed Long-Term Variable Remuneration. Regardless of other conditions and requirements that may be established, in order for each of the Participants to have the right to receive the respective shares, they must maintain an employment or commercial relationship with the Telefónica Group at the delivery date for each cycle (without prejudice to any exceptions deemed appropriate) and have been related to it for at least one year. Participants shall not receive the shares to which they may be entitled until the Nominating, Compensation and Corporate Governance Committee and the Audit and Control Committee have taken the actions described above. 7.- Date for delivery of the shares: the shares shall be delivered at the end of each cycle, i.e., in 2024, 2025 and 2026, respectively, with the specific delivery date to be determined by the Board of Directors or the body or person to which it delegates such power. 8.- Source of the shares to be delivered: subject to compliance with the legal requirements established for such purpose, the shares to be delivered to Participants may be (a) treasury shares of Telefónica, S.A. that either Telefónica, S.A. itself or any company of its Group has acquired or acquires; or (b) newly- issued shares of Telefónica, S.A. 9.- Malus and clawback clauses: the Board of Directors, following a report of the Nominating, Compensation and Corporate Governance Committee, shall assess the suitability, in relation to any of the cycles, of: (i) the total or partial cancellation of the payment of the shares pending delivery (malus), and/or (ii) the full or partial recovery of the shares delivered within twenty-four months of delivery thereof

Telefónica, S.A. ORDINARY GENERAL SHAREHOLDERS’ MEETING 2021 68 of 72 (clawback), under certain exceptional circumstances affecting the results of the Company, or resulting from improper conduct of the Executive Director. For these purposes, exceptional circumstances to be evaluated by the Board of Directors shall include the following, by way of example: • Reformulation of the Company's financial statements for reasons other than a change in applicable accounting standards. • In the event that an Executive Director has been disciplined for a serious violation of the code of conduct or other internal rules applicable thereto, or for a serious violation of the legal provisions also applicable thereto. • In any event, if it becomes clear that the delivery of the shares corresponding to the Plan has occurred wholly or partly on the basis of information which is clearly shown thereafter to be false or inaccurate or based on circumstances neither anticipated or accepted by the Company, and that have a material adverse effect on the income statement. • If the Company’s external auditor makes qualifications to its report that detract from the results taken into consideration in order to determine the amount of the variable compensation to be paid. 10.- Holding obligation and commitment to permanently hold shares: in any event, 100% of the shares delivered to the Executive Directors under the Plan shall be subject to a two-year holding period. Pursuant to the Directors’ Remuneration Policy of Telefónica, S.A., the Executive Directors must maintain (directly or indirectly) a number of shares (including those delivered as compensation) equivalent to twice their annual gross Fixed Remuneration, for so long as they remain on the Board of Directors and perform executive duties. For so long as such requirement is not met, any shares delivered under the Plan to the Executive Directors shall be subject to a holding period of three years. The foregoing shall not apply to shares that the Executive Directors need to sell in order to cover costs relating to the acquisition thereof or, with the approval of the Nominating, Compensation and Corporate Governance Committee, to handle extraordinary unexpected situations that require such sale. The Board of Directors may extend the above restrictions to other Participants. To empower the Board of Directors, to the broadest extent possible, with the Board of Directors being able to delegate such powers to the Executive Committee, the Nominating, Compensation and Corporate Governance Committee, the Executive Chairman of the Board of Directors, the Chief Operating Officer, or any other person expressly empowered by the Board of Directors for such purpose, to implement this resolution and to implement, develop, formalize, execute and settle the Plan at the time and in the manner that it deems appropriate, adopting such resolutions and executing
