Siltronic AG, a leading provider of high-tech wafer solutions, has been readmitted to the MDAX stock index as of June 22, 2026. The company’s shares now rank among the 50 largest publicly traded mid-cap companies in Germany, according to Deutsche Börse AG’s quarterly review. The readmission follows a positive trend in Siltronic’s free-float market capitalization over recent months. The shares also remain listed on the TecDAX index.
Dr. Michael Heckmeier, CEO of Siltronic AG, expressed satisfaction with the development. “We are very pleased to be readmitted to the MDAX. This is a strong vote of confidence from the capital markets in our strategy and our long-term growth prospects, which are driven by global megatrends such as artificial intelligence,” he said.
The inclusion underscores the company’s strategic alignment with the semiconductor industry’s expansion, particularly fueled by AI demand. Siltronic produces wafers that form the foundation for chips used in applications ranging from servers and smartphones to electric vehicles and wind turbines. The company operates facilities across Asia, Europe, and the United States, employing around 4,300 people worldwide.
The MDAX inclusion is based on free-float market capitalization, a key metric assessed during Deutsche Börse’s quarterly index reviews. Siltronic had been a member of the MDAX previously but was removed after a decline in market value. The recent upturn reflects broader market trends and the company’s positioning in the high-growth semiconductor sector.
Siltronic AG has been listed in the Prime Standard of the German Stock Exchange since 2015. The company’s return to the MDAX is expected to enhance its visibility among investors and potentially attract additional capital. As AI continues to drive demand for advanced chips, Siltronic’s role as a supplier of high-quality wafers positions it to benefit from long-term industry growth.
