Solvay (ISIN unavailable) was trading at EUR 25.16 on Euronext Brussels on September 24, 2026, down 1.26 percent from the prior close of EUR 25.48. The move comes as the chemicals group weighs a strategic partnership for its rare earths business.
Rare earth talks stay central
Solvay confirmed on September 8, 2026, that it was discussing a potential partnership with One Investment Management, or OneIM, for the rare earths business, according to Globenewswire. The company said the discussions might not result in an agreement or transaction.
That wording keeps the potential transaction separate from Solvay's operating base. The stock's EUR 25.16 price stood EUR 4.70, or 15.74 percent, below its 52-week high of EUR 29.86 on September 24, 2026, while remaining EUR 1.62 above the 52-week low of EUR 23.54.
Taiwan capacity adds a growth angle
Solvay is also expanding its electronic-grade hydrogen peroxide business in Taiwan. By the end of 2026, capacity at its Shinsol Advanced Chemicals joint venture is planned to rise from 35,000 tonnes annually to more than 70,000 tonnes, according to Reuters. The unit represented 15 percent of Solvay's total peroxides business in 2025, and the company targets at least a threefold increase in its contribution within five to seven years.
The figures point to a company pursuing targeted specialty-chemical growth while investors assess the value and timing of the rare earths discussions. The contrast is material: the Taiwan project has defined capacity milestones, whereas the partnership remains an active negotiation.
Stock remains below yearly high
Solvay's market capitalization was EUR 2,628,655,460 at the September 24, 2026, quote. The EUR 25.16 intraday price, a 1.26 percent decline, places the shares closer to the yearly low than the yearly high and gives the rare earths talks direct relevance for valuation expectations.
