Introducing the 2025 Sustainability Report

2025 has been a watershed year, an intense year in which, in addition to meeting our annual targets, we have made significant progress toward the goals set out in the 2024–2026 Strategic Plan #EnergizingFuturesTogether, reinforcing and strengthening Arteche’s foundations for the future. Now that we have passed the halfway point of this plan, we are ahead of our target figures, and the work we have done is beginning to be reflected in concrete results—both in our technological capabilities and in our presence in key markets.

Furthermore, we have accelerated our strategic business areas: T&D Automation and Grid Reliability. This growth is helping to shape the Arteche of the future thanks to our core pillars: Innovation, Sustainability, and Talent. Some of the year’s key milestones:

• The first is the effort we are making to expand our production capacity at a time when delivery times and service are key factors in our customers’ purchasing decisions. We have been increasing capacity across our various business lines for several years, but in 2025 we have bolstered our investments in high-voltage measurement and monitoring capacity with new facilities and laboratories in Mungia, China, and Mexico.
• We have also significantly advanced our strategy in the Grid Reliability pillar, a business with great future growth potential driven by the expansion of renewable generation and investment in the reinforcement and digitalization of transmission and distribution networks—and one of the key challenges of our strategic plan. This significant effort, within the Power Quality business, has resulted in the integration of RTR Energía and the launch of Amets Power Electronics—the project we have launched in partnership with MONDRAGON to advance power electronics—positioning us today in a technology that will be essential tomorrow. These two new companies, along with progress in bringing to market the storage solutions we’ve had since our entry into Teraloop last year, strengthen our production capabilities, our technology and service offerings, and reinforce our role in advanced solutions for the energy transition.
• Our focus on innovation—both in terms of product development and fostering the innovation ecosystem and acquiring new technologies—is bearing fruit. One need only look at the evolution of our product range to see this. Sustainable insulation, new relays, advancements in our protection and control range and recloser range, as well as new designs and processes in our most innovative and sustainable metering range, are the result of the development team’s hard work. But innovation and digitalization have also played a special role in 2025. Arin Technologies, the partnership signed with Elewit in the field of asset management and substation virtualization, is an example of this.

All this progress is underpinned by a firm commitment to sustainability, safety, and good governance. We have continued to make strides in reducing emissions, using resources efficiently, and creating skilled jobs, while strengthening the mechanisms that ensure transparent and responsible management. The progress on our roadmap is clear, as demonstrated not only by the data but also by external ratings. We have received an update to our CDP certification, which measures our commitment to reducing our carbon footprint, and our rating has risen from B to A, placing us among the top-ranked companies in our sector. We have also maintained our silver rating in the Ecovadis certification, with an increase in our overall score.

And all of this is being recognized by those around us, as evidenced by the Global Innovation Award granted by Iberdrola. Beyond the recognition, it represents the validation of a collaborative model based on continuous improvement, active listening, and the development of solutions that support our customers in their own technological evolution wherever they are, in more than 175 countries.

If there is one thing I am certain of, it is that none of these advances would be possible without the contribution and joint effort of everyone who makes up Arteche. Without that atmosphere of collaboration, shared purpose, support, and also the high standards that set us apart, this would not be possible. Because the energy that drives Arteche is the people who make it up.

We look toward 2026 with special motivation. We will celebrate our 80th anniversary, a milestone that invites us to remember where we came from and, above all, to imagine how far we can go. And we do so with a challenge that was approved at the General Meeting in December: to continue growing in the market with Arteche’s listing on the Continuous Market.

A step that will allow us to continue growing, innovating, and jointly building an increasingly solid, international, and sustainable company.
