Enpro Inc. Prices Offering of $450 Million 6.125% Senior Notes Due 2033

Enpro Inc. (NYSE:NPO) today announced the pricing of its previously announced offering of senior notes due 2033 (the "Senior Notes"). The face value of the Senior Notes is $450 million with an annual interest rate of 6.125%. The Senior Notes were priced at 100.0% of the face value. The offer was made in the United States to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the "Securities Act"), and to non-U.S. persons in reliance on Regulation S under the Securities Act. The Senior Notes offering is expected to close on May 29, 2025.

Enpro intends to use the net proceeds from the offering to fund the redemption of all of its outstanding 5.75% senior notes due 2026 (the "Outstanding Notes"), to repay a portion of the borrowings under its senior secured revolving credit facility used to fund the repayment on April 9, 2025 of all of its then-outstanding term loans under its senior secured credit facility, and to pay fees and expenses in connection with the offering. The conditional redemption of the Outstanding Notes was announced by Enpro on May 13, 2025.
