2026 General Shareholders' Meeting Participation Portal

Key information about the Participation Portal

General Shareholders' Meeting

The next General Shareholders’ Meeting is scheduled to be held at the Company’s registered office (Plaza Euskadi, 5, Bilbao) on Friday 29 May 2026, at 10:30 a.m. (first call), with shareholders and proxy representatives being able to participate remotely through this website.

Shareholders and their proxy representatives can attend the Meeting through the Participation Portal, as well as grant a proxy or cast a vote prior to the Meeting.

What credentials/information are needed to access the portal?

  • Shareholders

    Individual shareholders can authenticate themselves with their OLS Shareholders’ Club password and total number of shares (both as owner and co-owner), using either a recognised electronic certificate issued by the Royal Spanish Mint (FNMT), or their DNIe. 

    Furthermore, shareholders who are members of the OLS – Shareholders’ Club, or whose shares are held at deposited with entities that provide Iberdrola with the e-mail address of their customers, may also authenticate themselves by entering the QR code included in the proxy and absentee voting card that Iberdrola will send them by e-mail.

    Shareholders who are legal persons must authenticate themselves with a recognised electronic signature issued by the Royal Spanish Mint.

  • Representatives

    Proxy representatives can log in to the Participation Portal and send us a scanned copy of the card signed by the shareholder they represent to verify that they have been granted their proxy. Once verified, the proxy representatives will receive a proxy code with which they can be authenticated.

    Representatives of legal entities without a recognised electronic signature may grant a proxy or cast an absentee vote through the Participation Portal by submitting an image of the proxy and absentee voting card and by authenticating their powers to attend the General Meeting by submitting a scanned copy of the card and their power of attorney.
