STMicroelectronics and Centrica Energy sign long-term agreement for

the supply of electricity produced from renewable sources in Italy

• 10-yearcontract for energy produced by a new solar farm in Italy
• PPA will support 2027 carbon neutral and 100% renewable energy sourcing goals of semiconductor manufacturer with 2 large-volume manufacturing sites in Italy

Geneva (Switzerland) and Aalborg (Denmark), April 11, 2024 - STMicroelectronics, (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications, and Centrica Energy Trading A/S ("Centrica Energy") announced today that they have signed a ten-year Power Purchase Agreement (PPA) for the supply of renewable energy to its operations in Italy, starting January 2025. The agreement is based on the sale by Centrica of approximately 61 GWh of renewable energy per year, produced by a new solar farm in Italy. In Italy, ST operates two high-volume semiconductor manufacturing sites in Agrate (near Milan) and Catania as well as multiple R&D, design, and sales and marketing sites.

Geoff West, EVP and Chief Procurement Officer, STMicroelectronics, commented: "This second power purchasing agreement in Italy marks yet another important step towards ST's goal of becoming carbon neutral in its operations (Scope 1 and 2 emissions, and partially scope 3) by 2027, including the sourcing of 100% renewable energy by 2027. PPAs will play a major role in our transition. Starting in 2025, this PPA with Centrica will provide a significant level of renewable energy for ST's operations in Italy, which includes R&D, design, sales and marketing and large-volumechip manufacturing."

Kristian Gjerløv-Juel, Vice President for Renewable Energy Trading & Optimisation, Centrica, said: "We're pleased to have signed this agreement with STMicroelectronics. Centrica Energy continues to expand its capabilities and through this collaboration we will bring renewable energy to one of Europe's biggest technology companies. This agreement is another example of how Centrica is developing powerful value propositions for partners and customers globally."
