Iberdrola approaches £125 billion market capitalisation on its 125th anniversary

Iberdrola has reached the milestone of €125 billion in stock market value at the start of 2026, the year that marks the 125th anniversary of the founding of Hidroeléctrica Ibérica in Bilbao, the seed of the company that led to the creation of Iberdrola in 1992.

The company, which is at an all-time high, rose in value by nearly 40% in 2025, closing its fourth consecutive year of growth after the 2020 pandemic.

In fact, Iberdrola is now the leading utility in Europe by market capitalisation and the second largest in the world.

Hidroeléctrica Ibérica was founded in Bilbao on 19 July 1901 by engineer Juan de Urrutia with capital from Banco de Vizcaya. It then merged with Saltos del Duero in 1944 and later with Hidroeléctrica Española in 1992 to form Iberdrola.

To continue growing, its Strategic Plan for 2025-2028 envisages €58 billion in investments, with 65% earmarked for networks, mainly in the United Kingdom and the United States.

This plan envisages 40% growth in the regulated asset base of electricity networks to reach €70 billion in 2028, consolidating Iberdrola as a leader in critical infrastructure. It also forecasts that gross operating profit (EBITDA) will exceed €20 billion in 2028.

During 2025, Iberdrola strengthened its global position with far-reaching strategic moves. It completed the purchase of Electricity North West (ENW) in the United Kingdom and increased its stake in Neoenergía in Brazil, strengthening its regulated network business.
