Pursuant to the Corporate Enterprises Act, remote attendees who, in the exercise of their rights, intend to intervene in the Meeting and, if applicable, request information or clarifications regarding the items on the Agenda, the information accessible to the public that the Company has provided to the National Securities Market Commission since the last General Meeting was held (June 4, 2024) or regarding the auditor's report, or make the proposals permitted by Law, may assert these rights in real time in writing or by audio or video, by following the steps below:

• In writing: shareholders and proxies who wish to assert the above rights in writing must formulate their intervention, question or proposal in writing and send it to the Company through the Remote Attendance Platform as from their registration as a remote assistant on the day of the Meeting in accordance with section 1 above to when the Chair of the Meeting indicates at the Meeting that the floor is closed for speeches.
  Any interventions made by the remote attendees in writing will be available to all attendees on the Remote 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 assert the above rights by audio or video must request to intervene by any of these means through the Remote Attendance Platform, following the instructions provided in the Remote Attendance 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). Before speaking, speakers must ensure that access to their microphone and/or camera is enabled. It is recommended to use a stable internet connection and to charge the device fully or keep it plugged into the power supply during the course of the meeting and, in particular, during the time of the relevant intervention.

Any shareholders and proxies attending the General Meeting by remote means who need assistance may contact the Shareholder Service Office during the course of the meeting, by calling 900 100 182 or, if applicable, the additional telephone numbers provided by the Company for this purpose and posted on its website (www.redeia.com), or through the email address 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 Remote 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 Remote 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 remotely may cast their vote on the proposals relating to the items included on the Agenda through the relevant voting form enabled on the Remote Attendance Platform of the corporate website and in accordance with the operating rules provided there, from the time of their connection as a remote 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 by remote means 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 Remote Attendance Platform. 

Pursuant to the Regulations of the General Meeting, votes in favor of all the proposals of the Board relating to matters included on the Agenda will be deemed to be those of all the shares present or represented, with the exception of those of the shares corresponding to the attendees who selected to vote against, cast blank votes or abstain in the Remote 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 selected to vote against, cast blank votes or abstain in the Remote Attendance Platform. Making the relevant selection in the Remote Attendance Platform will be considered for all purposes as the communication to the Notary of the sense of the vote or abstention 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 who wish to notify the Notary their express withdrawal from the Meeting must do so by sending an electronic notice to the Notary through the "Communications to the Notary" section of the Remote Attendance Platform. 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 adopt appropriate measures in relation to mechanisms for remote attendance at the Meeting when necessary or dictated by technical or security reasons. The Company may not be held liable for any damage that may be caused to Shareholders arising from malfunctions, overloads, faulty lines, connection problems, technological incompatibilities or any other cases of the same or similar nature that are beyond the Company's control and prevent or affect the use of the remote attendance mechanisms for the Meeting (whether they refer to registration, intervention, voting, notifying the notary or any other action related to attendance at the Meeting), or due to the occasional lack of availability of its website, without prejudice to adopting the measures required in each situation, including the possible temporary suspension or postponement of the General Meeting if necessary to ensure the shareholders and their representatives may fully exercise their rights.

Personal attendance at the General Meeting by remote means will have the effect of revoking the proxy granted and the vote previously cast by any means of remote communication.

The personal remote attendance of the shareholder's proxy, whether the proxy has been granted on paper or by electronic means, will revoke the previous vote made by any remote procedure.

Shareholders and proxy holders who are legal entities and non-residents in Spain must consult with the Company on how to manage the procedure for remote proxies, voting and request for information with the due guarantees (verification and authentication of proxies), obtaining user/key credentials and the use of the Remote Attendance Platform and its peculiarities, through the Shareholder Service Office (located at the Company's registered office, Paseo Conde de los Gaitanes nº 177, La Moraleja, 28109, Alcobendas, Madrid), from Monday to Friday, excluding holidays, from 10:00 a.m. to 2:00 p.m. (CEST), at the shareholder service telephone number 900 100 182, from Monday to Friday from 8:00 a.m. to 6:00 p.m. (CEST) and, if applicable, at the telephone numbers that the Company provides for this purpose and posts on its website (www.redeia.com), or through the email address juntaaccionistas@redeia.com or accionistas@redeia.com. 

It is recommended for shareholders and proxies who are legal entities and who wish to obtain user/key credentials to attend the General Meeting through the Remote Attendance Platform accessible on the corporate website (www.redeia.com), to carry out the processes described in this procedure without delay. This will allow them to have the necessary user/key credentials for this purpose sufficiently in advance.

It will be the sole responsibility of shareholders (or their proxies) to safeguard their access credentials and electronic certificates, as well as their signature creation data and their signature creation device. The Company is not liable for the misuse, custody or conservation of these elements.
