Lausanne – At the Extraordinary General Meeting on 5 October 2026, the shareholders of Alpiq Holding Ltd. elected Alberto de Paoli as a new member of the Board of Directors, as proposed. The international energy executive will succeed Johannes Teyssen as Chairman of the Board of Directors on 15 October 2026.

Alberto de Paoli (1965) has more than 30 years of international leadership and management experience, spanning telecommunications, energy, finance and strategy, with a particular focus on leading companies through major industrial transformations. During his career at Enel, one of Europe’s largest energy companies, he held several senior leadership positions, including Group CFO and, most recently, General Manager with responsibility for the Group’s international activities outside Italy and Spain. He played a central role in Enel’s strategic transformation and international growth, with extensive experience in both organic growth through large-scale investment programmes, particularly in the energy transition, and external growth through major M&A and transformation transactions. He also served as CFO of Enel Green Power, overseeing its initial public offering, and headed Enel’s Group Strategy function.

“I would like to thank the shareholders for their trust. Alpiq is entering an exciting new phase, building on strong foundations and a clear strategy for growth,” says Alberto de Paoli. “I am particularly attracted by the company’s ambition to play a leading role in flexibility and in the transformation of the European energy system. Throughout my career, I have seen that the energy transition can succeed only when sustainability, security of supply and economic value creation reinforce each other. I look forward to working with the Board of Directors, CEO Antje Kanngiesser and the management team to support Alpiq in this next phase of growth and transformation.”

The Board of Directors thanks Johannes Teyssen for his tireless efforts and valuable contribution over the past five years. During his tenure, Johannes Teyssen played a significant role in shaping the company. Alpiq successfully navigated the energy crisis, strengthened its financial position and laid the foundations for the implementation of its growth strategy. On 26 August 2026, Johannes Teyssen informed the Board of Directors that he would step down from his position in autumn 2026. He will leave the Board on 15 October 2026 after five years at its helm.
