On July 1, 2026, Core & Main LP, a Florida limited partnership ("Core & Main") and indirect wholly-owned subsidiary of Core & Main, Inc. (the "Company") issued $750 million aggregate principal amount of 6.000% Senior Notes due 2034 (the "Notes") pursuant to an indenture, dated July 1, 2026 (the "Base Indenture"), among Core & Main, the Guarantors (as defined below) and U.S. Bank Trust Company, National Association, as trustee (the "Trustee"), as further supplemented by the first supplemental indenture, dated July 1, 2026 (the "Supplemental Indenture" and, together with the Base Indenture, the "Indenture"), among Core & Main, the Guarantors and the Trustee. The Notes are guaranteed on an unsecured senior basis by Core & Main's direct and indirect parent companies, Core & Main Midco, LLC and Core & Main Intermediate GP, LLC, and any of Core & Main's future wholly-owned domestic subsidiaries that will be a borrower under, or that will guarantee Core & Main's obligations under, Core & Main's existing senior secured credit facilities (collectively, the "Guarantors"). The Notes were offered and sold either to persons reasonably believed to be "qualified institutional buyers" pursuant to Rule 144A under the Securities Act of 1933, as amended (the "Securities Act") or to persons outside the United States under Regulation S of the Securities Act.

Pursuant to the Indenture, interest on the Notes will accrue at a rate of 6.000% per annum payable semiannually in arrears on January 1 and July 1 of each year, commencing on January 1, 2027. The Notes will mature on July 1, 2034, subject to earlier repurchase or redemption. Core & Main intends to use the net proceeds from the offering of the Notes to prepay a portion of its 2028 Senior Term Loan (as defined below) and for general corporate purposes, including investment in organic growth and operational initiatives, mergers and acquisitions, share repurchases, and other initiatives aligned with Core & Main's capital allocation strategy.

Core & Main may redeem the Notes, in whole or in part, at any time on or after July 1, 2029 at certain specified redemption prices set forth in the Indenture. In addition, at any time prior to July 1, 2029, Core & Main may redeem the Notes, in whole or in part, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, to but not including, the redemption date plus an applicable "make-whole" premium. At any time prior to July 1, 2029, Core & Main may also redeem up to 40.0% of the aggregate principal amount of Notes issued under the Indenture with net cash proceeds of certain equity offerings at a redemption price equal to 106.000% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, to but not including the redemption date.

The Indenture contains customary events of default, including, among other things, payment default, failure to comply with covenants or agreements contained in the Indenture or the Notes and certain provisions related to bankruptcy events. The Indenture also contains customary negative covenants.

The foregoing description of the Indenture and the Notes is qualified in its entirety by reference to the Base Indenture and the Supplemental Indenture, which are filed as Exhibits 4.1 and 4.2, respectively, to this Current Report on Form 8-K and are incorporated herein by reference. This Current Report on Form 8-K does not constitute an offer to sell or the solicitation of an offer to buy the Notes or any other security and shall not constitute an offer, solicitation or sale of the Notes or any other security in any jurisdiction in which such offering, solicitation or sale would be unlawful.
