Breaking Down Solvay SA Financial Health: Key Insights for Investors

From its founding by Belgian chemist Ernest Solvay in 1863-when the Solvay process reinvented soda ash production-to a modern group reshaped by the 2023 demerger that created Syensqo, Solvay SA today navigates transformation with bold moves like its 2024 plan to supply rare earths from La Rochelle and a 2025 ramp-up aiming to meet 30% of Europe's demand for magnets; publicly traded as SOLB on Euronext and a BEL 20 constituent, Solvay had a market capitalization of about €2.81 billion as of December 2025, employs roughly 9,000 people across 44 production sites and 6 research centers in over 41 countries, and under CEO Philippe Kehren balances two core segments-Basic and Performance Chemicals-while pursuing sustainability (carbon neutrality by 2050) and cost-saving targets such as gross savings of €350 million annually by 2028, even as 2025 brought headwinds in Soda Ash, an EBITDA outlook revision, and the Salindres plant closure with the loss of over 68 jobs; read on to explore Solvay's history, ownership, mission, operational model, revenue streams and market positioning in full detail.

Solvay SA (SOLB.BR): Intro

• Founded: 1863 (Ernest Solvay)
• Demerger: 2023 - creation of Syensqo (specialty chemicals); Solvay retained essential chemistry and advanced materials
• 2024 strategic pivot: announced supply of rare earth metals for permanent magnets from La Rochelle (France)
• 2025 expansion: La Rochelle rare earth processing scaled to target ~30% of Europe's demand for these materials
• 2025 operational pressures: Soda Ash segment hit by a soft market, prompting a downward revision of 2025 underlying EBITDA outlook
• 2025 restructuring: announced closure of Salindres plant (southern France), impacting 68+ jobs

• 1863-1900: Invention and commercialization of the Solvay process; rapid expansion into soda ash and related chemicals.
• 20th century: Diversification into polymers, specialty chemicals and global manufacturing footprint.
• 2010s-2020s: Strategic shift toward higher-margin specialty and sustainable businesses (composites, specialty polymers, battery materials).
• 2023: Corporate demerger creating Syensqo to focus on certain specialty activities; Solvay refocused on essential chemistry, advanced materials and growth in electrification and sustainability markets.
• 2024-2025: Investment in rare earth processing at La Rochelle to supply EV and wind-turbine magnet markets; capacity goal to cover ~30% of Europe's demand by 2025.

• Mission: develop chemistry that addresses key societal challenges (decarbonization, circularity, electrification, lightweighting).
