Iberdrola organises Shareholders’ Day in San Sebastián ahead of its General Meeting on 29 May

Iberdrola has held a new edition of its Shareholders’ Days in San Sebastián, part of a series of in-person meetings taking place across several Spanish cities ahead of the General Shareholders’ Meeting scheduled for 29 May.

Following the success of previous years, the Group has tripled the number of host cities, reinforcing its commitment to shareholder engagement and to fostering a close relationship based on active listening.

The series began in Valencia and, following Zaragoza and San Sebastián, and will continue on 5 May in Pamplona, on 13 May in Madrid and on 26 May in Bilbao. Based on previous editions, Iberdrola expects total attendance to exceed 2,000 shareholders.

As part of the company’s 125th anniversary celebrations, the Investor Relations team presented to shareholders in Aragon the key factors that have positioned Iberdrola as a global leader. The presentation highlighted the company’s transformation over the past 25 years, the main figures of its Strategic Plan through to 2028, and its strong performance in the 2025 financial year, in which Iberdrola once again recorded a record net profit of more than €6.2 billion.

The Shareholders’ Days have become a well-established forum for direct dialogue, allowing participants to learn first-hand about the milestones shaping Iberdrola’s development, engage with the management team, take part remotely in the General Shareholders’ Meeting and receive the traditional commemorative gift.

‘125 Light Years’ Exhibition

Attendees at the San Sebastián event were able to visit the ‘125 Light Years’ exhibition, launched to mark Iberdrola’s 125th anniversary. Through a series of photographs and videos,

the exhibition showcases the company’s evolution, its innovative spirit and its close connection with society.

The exhibition presents photographs from the company’s early years in the Basque Country, including historical images of Bilbao and the founding of Hidroeléctrica Ibérica in the early 20th century. It features iconic architecture, early electrical infrastructure, and original documents that trace the emergence of the business. It also showcases scenes of industrial development linked to electricity generation and supply, alongside the group’s evolution through to more recent milestones, such as the Torre Iberdrola, a landmark that symbolizes its long-standing presence and influence in the Basque Country.

Strengthening shareholder engagement and participation

The General Meeting will be held both in-person and remote participation options. The company has provided shareholders with extensive facilities to engage remotely in advance of the meeting via the corporate website, the shareholder helpline, instant messaging and postal voting. A key advantage is that the proxy voting card consolidates all of a holder’s shares, regardless of where they are held. This simplifies and streamlines participation, while also enhancing security through the inclusion of a QR code and access code.

Iberdrola continues to reinforce its open, accessible and sustainable General Meeting model, which includes ongoing dialogue channels such as the Shareholder Office, the Investor Relations Office and the Virtual Shareholder Assistant.

As part of the agenda for the General Meeting, and in line with its commitment to shareholder remuneration, the Board of Directors will propose a supplementary dividend of €0.427 per share, in addition to the €0.253 per share already paid on 2 February as an interim dividend. Iberdrola will therefore allocate €4.5 billion to dividends for the 2025 financial year.

In addition, the company will propose a participation dividend of €1 gross for every 200 shares, subject to the General Meeting reaching a quorum of 70% of share capital.
