Iberdrola has announced that the company has placed EUR 1 billion in green hybrid bonds. The bond is perpetual but has a repurchase option that begins in August 2031. The coupon was set at 3.75 percent, making it the lowest of all the hybrids issued this year, and also the lowest in this type of transaction since March 2022, the company stated.

As it did with its senior bond in May this year, Iberdrola complies in this issue not only with the ICMA Green Bond Principles, but also with the new European Union Green Bond Standard. This makes it the first green transaction under this format in a hybrid bond.

The demand registered reflected high investor interest in Iberdrola, reaching more than EUR 8 billion, which allowed the company to issue more than initially considered, and an oversubscription of 8 times the final offer, substantially reducing the expected cost. This was made possible by the participation of more than 400 qualified international investors, mainly from Europe and the United Kingdom. In addition, more than 87 percent of the participation corresponds to sustainable investors or those aligned with the United Nations Principles for Responsible Investment.

The company has taken advantage of the favourable market window that emerged after its results were presented, with costs at annual lows and in anticipation of central bank meetings in the United States and Europe, as well as an increase in competitive supply starting next week.

Nine leading international banks participated in the placement: Barclays, Deutsche Bank, Mizuho, CACIB, MUFG, ING, Intesa, Wells Fargo, and Caixabank, which facilitated access to investors.

The main areas covered by the operation are the United Kingdom (31 percent), France (19 percent), Germany (16 percent), Asia (5 percent), the United States and Canada (3.5 percent), and the Nordic countries (2.5 percent). By type of investor, almost 86 percent correspond to investment funds.

The volume of demand and the conditions set once again demonstrate the level of confidence of the market and investors in the soundness and solvency of the Group's business and growth plans. This transaction will serve to refinance a similar transaction that will be repurchased in the near future, maintaining the company's hybrid volume stable at EUR 8.25B, as committed by the issuer at its recent Capital Markets Day in London.

In accordance with the methodology of the main rating agencies, hybrid bonds count as 50 percent capital meaning that this transaction contributes to maintaining the group's credit ratings. Iberdrola's last issue of this type of debt was in November 2024 with a coupon of 4.247 percent.
