Iberdrola launches its remote participation campaign for the 2026 Annual General Meeting

Iberdrola is today launching its remote participation campaign for the Annual General Meeting, which has already been called for 29 May – more than two months in advance, double the minimum legal notice period – to facilitate the involvement of its hundreds of thousands of shareholders.

In this regard, from today, 20 March, a wide range of channels for proxy granting and absentee voting will be available until 28 May. These channels may be used by all shareholders who hold at least one share registered in their name.

The company, which is submitting its 2025 financial results for approval by its shareholders, arrives at the 2026 Annual General Meeting – marking its 125th anniversary – in a position of undisputed leadership as Europe’s largest electricity company and one of the world’s two largest by market capitalisation, having reached €135 billion.

In line with its commitment to shareholder remuneration, the Board of Directors is proposing to the Annual General Meeting a supplementary dividend of €0.427 per share, in addition to the €0.253 per share paid on 2 February as an interim dividend. Iberdrola will thus allocate €4.5 billion to dividends for the 2025 financial year.

In addition, Iberdrola proposes to distribute an engagement dividend of €0.005 per share to all its shareholders, subject to the General Meeting achieving a quorum of 70% of the share capital, once again applying an engagement policy based on transparency, active listening and constant dialogue.

Proximity to shareholders and greater incentives for participation

The General Meeting will be held both in person and remotely, with a wide range of options available for remote participation prior to the meeting via the corporate website, the shareholders’ telephone line, instant messaging and postal voting, thereby reinforcing the open, accessible and sustainable model for General Meetings that the Group has been developing over the years.

As additional incentives alongside the engagement dividend, Iberdrola is holding a prize draw for 30 electric bicycles open to shareholders participating via the website or the telephone line, and a commemorative gift may be collected at the shareholder information desks that will be available in the run-up to the General Meeting.

To mark the Annual General Meeting, the Company is strengthening and expanding its existing channels for ongoing communication with shareholders and investors, who now have access to the Shareholder Office, the Investor Relations Office and the Shareholder Virtual Assistant. Furthermore, it will hold conferences and face-to-face meetings in various cities across Spain, where attendees will be able to learn first-hand about Iberdrola’s strategy, as well as its outlook and key challenges for the future.

To attend online, shareholders must register on the website between 08:00 and 09:45 on the day of the General Meeting; those wishing to attend in person must reserve a seat at the Shareholder Office or via the corporate website by 09:45 on 29 May.
