Geneva, December 13, 2022 - STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications, has been recognized for leadership in corporate transparency and performance on water security by global environmental non-profit CDP, securing a place on its annual'A List'.

Based on data reported through CDP's 2022 Water Security questionnaire, ST is one of a small number of companies that achieved an'A' - out of nearly 15,000 companies scored.

CDP's annual environmental disclosure and scoring process is widely recognized as the gold standard of corporate environmental transparency. In 2022, over 680 investors with over US$130 trillion in assets and 280 major purchasers with US$6.4 trillion in procurement spend requested companies to disclose data on environmental impacts, risks, and opportunities through CDP's platform. A record-breaking

18,700 companies responded.

A detailed and independent methodology is used by CDP to assess these companies, allocating a score of A to D- based on the comprehensiveness of disclosure, awareness and management of environmental risks and demonstration of best practices associated with environmental leadership, such as setting ambitious and meaningful targets. Those that don't disclose or provided insufficient information are scored an F.

"Inclusion in the CDP's A List for Water is an important recognition of our continuous focus on water-related risks and comprehensive management approach, including water stress assessment, recycling, efficiency and conservation programs" said Rajita D'Souza, President, Human Resources and Corporate Social Responsibility. "ST continues to reduce our water footprint in all our operations and sites, to address all water risks throughout our supply chain and territories wherever we operate, and to further develop our positive impact and support for communities."

Sustainability has been central to ST's business model and culture for over 25 years. ST continually reduces its water footprint, while sustaining highest standards of wastewater treatment and control before being released into the environment. In 2021, water consumption per unit of production was reduced by 16% compared to 2020, in line with the 2025 target to reduce water consumption by 20% vs 2016.
