Telematic assistance

Shareholders (or their proxies) that wish to attend the General Meeting online must log on to the Online Attendance Platform enabled for that purpose on the Company's website (www.redeia.com) and register on the day of the General Meeting, namely, between 9:15 a.m. (CEST) and 10:45 a.m. (CEST) on May 12, 2026 at first call or on May 13, 2026 if the General Meeting is held at second call, as expected. Attendee registration will not be accepted outside this time range. Attendees who register for the first call session of the General Meeting must re-register to attend if the General Meeting is held at second call. Shareholders are reminded that, as already explained above, the time limit for emailing duly filled in and signed proxy cards not processed through the Company to juntaaccionistas@redeia.com or accionistas@redeia.com is 10:15 a.m. (CEST) on the day of the General Meeting. To attend the General Meeting, proxies must also have one of the means of proof of identity described below. In particular, those who need a username/password credential must obtain one from the Company before midnight (24:00 hours) (CEST) on May 11, 2026. 

To register to attend the General Meeting, attendees must prove their identity by one of the following means:

• A valid electronic certificate included in a National Identification Card.
• A recognized, valid electronic user certificate in force, pursuant to the applicable legislation, issued by the Spanish Public Certification Authority (CERES) affiliated with Spain's National Mint.
• The username/password credential that the shareholders (or their proxies) will receive at their email address,
  • The username/password credential that the shareholders (or their proxies) will receive at their email address (www.redeia.com), in the Corporate Governance section, General Meeting area; and 

  • for non-shareholders, upon request by sending an email to: juntaaccionistas@redeia.com or accionistas@redeia.com, including the following information:

    • Their first and last name(s) or company name, together with their Spanish national identification number, Spanish foreigner identification number, passport, or Spanish tax Identification number (or equivalent supporting document).
    • A digitalized copy of the public deed accrediting representation in the case of legal entities.
    • The valid email address where the username/password credential for participating at the General Meeting online in accordance with the notice of meeting and the operating rules and instructions and all other applicable documents posted on the Company’s website (www.redeia.com) is to be sent..

    In both cases, the username/password credential will be sent by email to shareholders (or their proxies) after verification of their identity, as established in the implementing rules and instructions.

    Credentials may be requested from midnight (00:00 hours) (CEST) on April 21, 2026 to midnight (24:00 hours) (CEST) on May 11, 2026. Shareholders (or their proxies) who wish to obtain username/password credentials are encouraged to do so without delay. 

    Once the information sent by shareholders (or their proxies) has been received, the Company will carry out the appropriate verifications, granting validity to the digitalized copies for these purposes provided that it has no reasonable doubts as to the identity of the subject, and will send the shareholder or proxy, through the email address communicated, the username/password credential so that they may attend the General Meeting and vote online.

    The Company reserves the right to ask shareholders and their proxies for any additional means of identification as it deems necessary to guarantee their identity.

In addition, for the proxy to be registered, the proxy must have been previously granted by the shareholder, which must have been accepted by the proxy, all in accordance with the terms set forth in the "Appointing proxy by remote means of communication before the Meeting" section of the notice of the meeting and in the rules published for this purpose on the Company's website (www.redeia.com).

To ensure the quality of the connection of the Online Attendance Platform and be able to send shareholders (or their proxies) the relevant information for ease of registration, also available on the Company's website (www.redeia.com), all shareholders (or their proxies) who intend to attend the General Meeting, and where appropriate take part in the deliberations, online are asked to send an email to the Shareholder Relations Office (juntaaccionistas@redeia.com or accionistas@redeia.com) before 8:30 a.m. (CEST) on May 11, 2026 or on May 12, 2026 if the General Meeting is held at second call, as expected. Apart from this prior notice, shareholders (or their proxies) must complete the registration process on the day of the General Meeting as described above. In addition, from the date of publication of this notice until the end of the General Meeting, shareholders (or their proxies) may contact the Shareholder Service Office, whose contact details appear in the "General Information" section of this notice, if they require assistance.

According to the Corporate Enterprises Act, online attendees who intend to exercise their rights and take part in the General Meeting deliberations and if appropriate request information or explanations regarding Agenda items, the publicly accessible information the Company has reported to the National Securities Market Commission since the last General Meeting (June 30, 2025), or the auditor's report, or make proposals as permitted by the Act, may exercise these rights in writing or by audio or video in real time by following the steps below:

• In writing: shareholders and proxies who wish to exercise the above rights in writing must formulate their statement, question, or proposal in writing and send it to the Company through the Online Attendance Platform between the time they register as online attendees on the day of the Meeting as per section 1 above and when the General Meeting Chair closes the floor to further debate.
  Any interventions made by remote attendees in writing will be available to all attendees on the Online Attendance Platform for consultation by any of them, at any time, from when the General Meeting is called to order. 
• By audio or vídeo: shareholders and proxies who wish to exercise the above rights by audio or video must request their turn to participate by either of these means through the Online Attendance Platform according to the instructions provided on that platform.
  To intervene in the General Meeting by audio or video, the attendee must use a device with an audio and, if applicable, video system (microphone and, if applicable, webcam) and allow the device to access those media.

Shareholders and proxies attending the General Meeting online who need assistance may contact the Shareholder Relations Office during the meeting by calling 900 100 182; if appropriate by calling any other telephone numbers provided by the Company for this purpose as posted on its website  (www.redeia.com), or by sending an email to juntaaccionistas@redeia.com or accionistas@redeia.com.

Shareholders (or their proxies) who intend to exercise their rights of intervention, information or proposal must express this intention when they register in the Online Attendance Platform.

Shareholders and proxies who would like their intervention to appear literally in the minutes of the meeting must expressly state so in the interventions section of the Online Attendance Platform or in their intervention. 

Any requests for information or clarifications made by the shareholders or their proxies during the General Meeting will be answered verbally during the meeting or in writing within seven days following the end of the meeting. 

Shareholders or their duly registered proxies attending the General Meeting online may cast their votes on the proposals relating to the items included on the agenda through the relevant voting form enabled on the Online Attendance Platform on the Company's website and in accordance with the operating rules provided there from the time of their connection as an online attendee in accordance with section 1 above.

Likewise, with respect to the proposed agreements on those matters that, by law, are not included on the agenda and may be dealt with at the meeting, those attending the meeting online may cast their votes from the moment those proposals are read out by the Secretary of the General Meeting and voting is enabled in the Online Attendance Platform.  

Pursuant to the General Meeting Regulations, votes in favor of all the proposals made by the Board relating to matters included on the agenda will be deemed to be the votes of all shares present or represented, with the exception of those of the shares held by attendees who have elected to vote against, cast blank votes, or abstain on the Online Attendance Platform. In turn, votes against all proposed agreements relating to matters not included on the agenda or alternative proposals to those of the Board will be deemed to be those of all shares present or represented, with the exception of those of the shares of the attendees who have elected to vote against, cast blank votes, or abstain in the Online Attendance Platform. Choosing the relevant selection on the Online Attendance Platform will be considered for all purposes as communication of ballots cast or abstentions to the Notary in the terms provided in each case. 

In relation to alternative proposals, it will be understood that a vote in favor of a proposed agreement will be held to be a vote against any alternative proposals that are incompatible with it.

The electronic voting process for all proposals submitted to the General Meeting will end when the Secretary of the General Meeting has finished reading the summaries of the proposals relating to the items included on the agenda. 

Attendees may inform the Notary that they are expressly withdrawing from the General Meeting by sending the Notary an electronic message via the Online Attendance Platform's "Communications to the Notary" section. Once they leave the meeting, any subsequent actions they make will be considered as not having been carried out.

The Company reserves the right to take appropriate measures in relation to the mechanisms for attending the General Meeting online where required for technical or security reasons. The Company will not be liable for any harm suffered by shareholders or proxies as a result of malfunctions, overloads, line failures, connection issues, technological incompatibilities, or any other reasons of that same or a similar nature outside the Company's control that prevent or affect use of the online attendance mechanisms for the General Meeting (whether in respect of registration, participation, voting, communications to the notary, or any other action relating to attendance at the Meeting) or as a result of the temporary unavailability of its website, without prejudice to taking whatever measures are required in each situation, potentially including temporary suspension or postponement of the General Meeting if necessary to ensure that shareholders and their proxies may exercise their rights in full.

In all matters not expressly provided for in this notice of meeting, remote attendance at the General Meeting will be subject to the rules on the Company's website  (www.redeia.com).
