Syensqo CEO Ilham Kadri Steps Down, Mike Radossich Takes the Helm

Brussels, Belgium – February 27, 2026 – Ilham Kadri is stepping down as CEO of Syensqo, the specialty chemical company spun off from Solvay in December 2023. Mike Radossich will succeed her, effective January 1, 2026, according to announcements made in September 2025.

A Transformative Tenure

Kadri, who also served as CEO of Solvay since 2019, oversaw the complex separation of the company into two independent entities: Solvay and Syensqo. She is credited with successfully creating two publicly listed companies with strong financial foundations [1]. Her two-year term as president of the European Chemical Industry Council (Cefic) will also conclude at the end of 2025 [2].

Mike Radossich: The New Leader

Mike Radossich currently serves as president of Syensqo’s Performance and Care and Other Solutions segments. He joined Solvay a decade ago through the acquisition of Cytec Industries [4]. Radossich will assume the role of CEO on January 1, 2026 [3].

Syensqo’s Performance and Market Position

Syensqo, headquartered in Brussels, Belgium, is a multinational chemicals and materials company with a global presence, operating 62 industrial sites and 12 major R&D centers across 30 countries [3]. The company employs approximately 13,000 people [3]. In 2024, Syensqo reported revenues of €6.8 billion and a net income of €3.792 million [3].

Recent financial reports indicated a decline in Syensqo’s second-quarter pre-tax profits, falling 8% to approximately $395 million, primarily due to lower performance in its specialty polymers business [2]. Financial analysts had previously questioned Kadri’s strategies for growing this key business unit [2].

Impact on the Belgian Stock Market

With Kadri’s departure, Anna Bertona of Azelis will be the sole female CEO of a BEL 20 company [4]. Syensqo is listed on the Euronext Brussels exchange under the ticker symbol SYENS and is a component of the BEL20 index [3].
