Item 7.01 Regulation FD Disclosure.

On November 10, 2025, Carpenter Technology Company (the “Company”) issued a press release to announce that it intends to offer, subject to market and other conditions, $700.0 million aggregate principal amount of senior notes due 2034 (the “Notes”) in a private offering (the “Offering”). A copy of the press release is attached hereto as Exhibit 99.1 to this Current Report.

The Notes have not been and will not be registered under the Securities Act of 1933, as amended (the “Securities Act”) or the securities laws of any other jurisdiction and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements of the Securities Act or the securities laws of any other jurisdiction. Accordingly, the Notes are expected to be eligible for resale in the United States only to persons reasonably believed to be qualified institutional buyers and outside the United States to non-U.S. persons in compliance with Regulation S. This announcement shall not constitute an offer to sell or a solicitation of an offer to buy any of these securities nor shall there be any sale of these securities in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state.

The Company is in the process of amending and restating its Second Amended and Restated Credit Agreement with Bank of America, N.A., as administrative agent, swing line lender and letter of credit issuer and the other lenders, agents and arrangers party thereto (the "Credit Facility"), subject to customary conditions (the “Amendment”). The Company expects that the Amendment, if entered into, will (i) increase the revolving commitments under the Credit Facility from $350 million of secured commitments to $500 million of unsecured commitments, (ii) increase the uncommitted accordion feature under the Credit Facility allowing for an increase to the revolving commitments and/or the establishment of new term loans by an aggregate amount not to exceed $650 million, (iii) extend the maturity date of the Credit Facility to the fifth anniversary of the closing of the Amendment, and (iv) modify certain other terms and covenants of the Credit Facility, including interest rates and financial covenant levels, as mutually agreed between the Company, the lenders party thereto and Bank of America, N.A., as administrative agent thereunder. The Company expects to close the Amendment concurrently with or prior to the closing of the Offering; however, there can be no assurance as to the outcome or timing of the Amendment.

The information in this Current Report, including the Exhibit attached hereto, shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section. The information contained herein and in the accompanying Exhibit shall not be incorporated by reference into any registration statement or other document filed with the Securities and Exchange Commission by the Company, whether before or after the date hereof, regardless of any general incorporation language in such filing, except as shall be expressly set forth by specific reference in such filing.
