Elementis plc

Response to Innospec Inc. announcement

The Board of Elementis plc ("Elementis" or the "Company") notes the announcement by Innospec Inc. ("Innospec") and confirms that on 31 March 2021 it received a conditional proposal from Innospec in relation to a potential offer for Elementis of 160p per Elementis share (the "Conditional Proposal"). The Conditional Proposal would have been satisfied in Innospec shares with a partial cash alternative available of up to 50% of the consideration together with a mix and match facility.

The Board, together with its management and advisers, assessed the Conditional Proposal against its rigorous valuation framework comparing it against an assessment of the fundamental value of Elementis as well as the likely value to be created by the continued delivery of its strategy and its medium term performance objectives.

The Board concluded that the Conditional Proposal significantly undervalued Elementis and fell meaningfully short of the value creation potential for Elementis shareholders based on Elementis' existing strategy. In addition, the substantial element of the consideration being in Innospec shares made this Conditional Proposal less attractive for Elementis shareholders. The Board's assessment is supported by the strong momentum in the business and by an encouraging start to 2021.

Accordingly, on 9 April 2021 the Board unanimously rejected the Conditional Proposal.

Andrew Duff, Chairman of Elementis, said:

"The Board firmly believes in the attractive value to be delivered for Elementis shareholders through the execution of our strategy. Against a significantly weaker demand environment in 2020 brought about by the Covid-19 pandemic, management took swift action to reduce costs and position the business for recovery. The business has good momentum and is delivering on its Innovation, Growth and Efficiency strategy with clear medium term objectives that will deliver significant value to Elementis shareholders. This Conditional Proposal does not reflect this value.

The Board of Elementis would always consider the merits of an engagement at a level that offers attractive value to its shareholders and that reflects the nature of its high margin activities with strong underlying growth prospects. However, having reviewed the Conditional Proposal from Innospec carefully, we are confident that the best value for shareholders will be delivered through the independent execution of our strategy and building on the encouraging start to trading in 2021."
