Solvay reserves the right to undertake a squeeze-out on any remaining Rhodia shares if it receives acceptances from more than 95% of the company's equity and voting rights following the offer.

With sales of EUR 12 billion² the new group will become a large global chemical company firmly committed to sustainable development. The future group will capitalize on its excellent market positions with 90% of combined sales realized in businesses where it is one of the top 3 worldwide market leaders.

Christian Jourquin, Solvay CEO stated: "The track record of both companies to date bears witness to the strong growth potential, based on their excellence and strong complementarities. These will enhance the development potential for the new group, which will be larger than those of Solvay and Rhodia on a standalone basis. This transaction will give the two companies the resources they require to pursue their track record of innovation and as such to meet their future industrial and technological challenges".

"The launch of the Solvay offer gives Rhodia shareholders the opportunity to properly value their investment, while also contributing to the creation of a major chemical group.
