NEW YORK, Oct. 01, 2026 (GLOBE NEWSWIRE) -- Minerals Technologies Inc. (NYSE: MTX) (“MTI”), a leading, technology-driven specialty minerals company, today announced the commencement of a private offering (the “Offering”) of $400 million aggregate principal amount of senior notes due 2034 (the “Notes”), subject to market and other conditions.

MTI intends to use the net proceeds from the Offering, together with cash on hand, (i) to redeem all of its outstanding 5.000% senior notes due 2028 (the “2028 Notes”) and (ii) to pay transaction fees and expenses related to the Offering and the concurrent amendment and extension of its revolving credit facility. This press release does not constitute a notice of redemption and does not constitute an offer to redeem or purchase, or the solicitation of an offer to sell, any of the 2028 Notes.

The Notes and the guarantees thereof will be offered in a private offering exempt from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”). The Notes and the guarantees thereof will be offered only to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act and to non-U.S. persons outside the United States in reliance on Regulation S under the Securities Act.

The Notes and the guarantees thereof have not been registered under the Securities Act and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act and applicable state laws.

This press release does not constitute an offer to sell, or the solicitation of an offer to buy, the Notes, nor shall there be any sale of the Notes in any state or jurisdiction in which such offer, solicitation, or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction. No assurance can be made that the Offering will be consummated on its proposed terms or at all.
