Madrid, 4 November 2025 – Cox’s Extraordinary General Meeting of Shareholders today approved the acquisition of 100% of Iberdrola México’s share capital, giving the green light to a transformational transaction that strengthens its position as a global water and energy utility and consolidates its leadership in one of its most strategic markets.

Through this acquisition, Cox, present in Mexico for more than a decade, gains access to a platform with 2,600 MW of installed operational capacity and the country’s largest private supplier, with a 25% market share and more than 20 TWh distributed among over 500 major clients.

The transaction positions Cox as a key player in the Mexican energy market, one of the countries it knows best among the nearly thirty in which it operates. Furthermore, it aligns with the new regulatory framework under the Plan México, which enhances legal certainty for foreign investment.
