STMicroelectronics Announces Changes to Euronext Trading Symbols

Geneva, March 6, 2023 - STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications, announces that effective Monday, March 13, 2023, prior to the stock exchanges market openings, the trading symbols of STMicroelectronics common shares listed on Euronext will change. For the former Borsa Italiana (MTA) listing in Milan, it will become ‘STMMI’. For the Euronext Paris listing in Paris, it will become ‘STMPA’.

Given the migration of the Borsa Italiana markets onto the Euronext trading platform, it was necessary to create two separate trading symbols, as now the two order books will be traded in the same environment.

The ‘STM’ trading symbol on the New York Stock Exchange remains unchanged.
