FOR IMMEDIATE RELEASE

10 December 2020

Minerals Technologies Inc. ("Minerals Technologies")Statement regarding Elementis plc ("Elementis" or "the Company")

Further to the decision by the Elementis Board to reject our increased all-cash possible offer for the Company of 130 pence per Elementis share, Minerals Technologies announces today that it does not intend to make an offer for Elementis under Rule 2.7 of the Code.

Minerals Technologies believes that its all-cash proposal of 130 pence per share was fair, based on information in the public domain, and disagrees with the views expressed by the Elementis Board in connection with its refusal to engage in discussions.

Minerals Technologies will remain disciplined in its approach to consolidation opportunities.

This is a statement to which Rule 2.8 of the Code applies.

For the purposes of Rule 2.8 of the Code, Minerals Technologies reserves the right to set aside the restrictions in Rule 2.8 in the following circumstances:

i. with the agreement of the Elementis Board;

ii. if a third party announces a firm intention to make an offer for Elementis;

iii. if Elementis announces a "whitewash" proposal (as referred to in Note 1 of the Notes on Dispensations from Rule 9) or a reverse takeover (as defined in the Code); and

iv. if there has been a material change of circumstances (as determined by the Panel on Takeovers and Mergers).
