Minerals Technologies Inc. priced a private offering of $400 million in aggregate principal amount of 7.500% senior notes due 2032 at 100.000% of principal. The offering is expected to close on Oct. 13, 2026, subject to customary closing conditions. MTI intends to use the net proceeds, together with cash on hand, to redeem all outstanding 5.000% senior notes due 2028 and pay transaction fees and expenses related to the offering and the concurrent amendment and extension of its revolving credit facility. The notes will be guaranteed by certain wholly owned domestic restricted subsidiaries and offered under Securities Act exemptions to qualified institutional buyers under Rule 144A and non-U.S. persons outside the United States under Regulation S. MTI cautioned that the offering may not close on its proposed terms or at all.
