What is the "Iberdrola Retribución Flexible" system?

All the information about the optional dividend system

“Iberdrola Retribución Flexible” is Iberdrola’s optional dividend system that allows shareholders to choose how they wish to receive their remuneration among three options:

  • i. Receive new fully paid-up shares of “Iberdrola, S.A.”.

  • ii. Sell their free allocation rights on the market.

  • iii. Receive their remuneration in cash through the payment of a cash dividend.

This system is implemented through a capital increase charged to reserves and the payment of a cash dividend. All shareholders receive one free allocation right for each share they hold on the record date, and those wishing to receive the cash dividend must expressly waive these rights.

Shareholders may combine any of the options with respect to different groups of shares they hold. The value of the remuneration received by shareholders under options (i) and (iii) above will be equivalent, regardless of the chosen option, in terms of market value and without prejudice to tax treatment. If the shareholder does not communicate their choice within the common election period, the default option will be to receive newly issued fully paid-up shares.

In the first edition of the “Iberdrola Flexible Remuneration” optional dividend system for 2026, implemented during the month of July, shareholders who choose the cash dividend will receive a total supplementary dividend of €0.427 gross per share. This amount is aligned with the so-called “target dividend”, which is the gross target amount per share that the Company considers appropriate to distribute in this edition in order to comply with its Shareholder Remuneration Policy and promote long-term value creation.

The Company has determined, in accordance with the formulas set out in the terms and conditions, that:

  • The number of free allocation rights required to receive one new share is 50.
  • The amount of the supplementary dividend is €0.425 gross per share.
  • The payment of the adjustment dividend is applicable and its amount is €0.002 gross per share. This dividend will be paid to all the Company's shareholders on the record date, regardless of the remuneration option they have chosen.

Accordingly, the target dividend of €0.427 gross per share envisaged for this edition of the system is achieved
.
