Solvay SA is a global chemical manufacturer with a legacy dating back to 1863, operating primarily in the essential chemicals sector. In December 2023, the company completed a major demerger, spinning off its specialty chemicals and advanced materials operations into a new independent entity, Syensqo. Today, the standalone Solvay operates through two main segments: Basic Chemicals, which includes its market-leading soda ash, sodium bicarbonate, and peroxides businesses, and Performance Chemicals, which covers silica, Coatis, and Special Chem (including rare earths and fluorine). The Basic Chemicals segment accounts for the majority of the company's revenue. Solvay operates over 40 industrial sites globally, providing foundational chemical products used in glass manufacturing, water purification, healthcare, and electric vehicle batteries.
