Insights

Debt Capital Markets Analyst

Issuance of fixed-rate senior notes increases funded debt with a 5.550% coupon to 2036.

The filing discloses a Form of 5.550% Senior Notes due 2036 and an Underwriting Agreement dated August 14, 2025, indicating a marketed debt offering using a registered shelf.

This increases near-term liquidity flexibility but also raises long-term interest expense; watch closing and offering size details in the prospectus supplement and the related August 18, 2025 news release for the exact proceeds and use of proceeds within days.

Corporate Counsel / Securities Attorney

Standard securities documentation and counsel opinions are included to support a registered note issuance.

The filing references the S-3 Registration Statement, existing indenture documents and includes the opinion and consent of Davis Polk & Wardwell LLP, consistent with a registered debt offering under the Securities Act.

Key legal items to confirm in the prospectus supplement are the final pricing terms, covenants under the supplemental indenture, and any registration/exchange features; these will determine investor protections and amendment mechanics after issuance.

LLC, as representatives of the several underwriters named therein, relating to the public offering and sale by the Company of $300.0 million aggregate principal amount of 5.550% Senior Notes due 2036 (the “2036 Notes”). The offering of the 2036 Notes closed on August 18, 2025. The 2036 Notes were issued pursuant to an indenture (the “Base Indenture”), dated as of March 28, 2013, between the Company and U.S. Bank Trust Company, National Association (successor to U.S. Bank National Association), as trustee (the “Trustee”), as supplemented by the First Supplemental Indenture (the “Supplemental Indenture”), between the Company and the Trustee, dated as of February 28, 2023, and the officers’ certificate issued in connection with the offering of the 2036 Notes, dated as of August 18, 2025 (the “Officers’ Certificate” and, together with the Base Indenture and Supplemental Indenture, the “Indenture”). The Company intends to use the net proceeds from the sale of the 2036 Notes to redeem all of the $175.0 million outstanding aggregate principal amount of its 6.10% Senior Notes due 2026 (the “2026 Notes”), to pay related premiums, fees and expenses and for general corporate purposes.

The 2036 Notes have been registered under the Securities Act of 1933, as amended (the “Act”), pursuant to a registration statement on Form S-3 (No. 333-276645) (the “Registration Statement”) previously filed with the U.S. Securities and Exchange Commission (the “SEC”) by the Company under the Act. A prospectus supplement relating to the offering has been filed with the SEC.

The above descriptions of the Underwriting Agreement, the Indenture and the 2036 Notes are qualified in their entirety by reference to the Underwriting Agreement, the Base Indenture, the Supplemental Indenture, the Officers’ Certificate and the form of the 2036 Notes. A copy of the Underwriting Agreement, the Base Indenture, the Supplemental Indenture and the form of the 2036 Notes are filed hereto and are incorporated by reference herein. The Underwriting Agreement, the Supplemental Indenture and the form of the 2036 Notes are also incorporated by reference into the Registration Statement. In addition, in connection with the offering of the 2036 Notes, Davis Polk & Wardwell LLP, acting as counsel to the Company with respect to the offering of the 2036 Notes, is filing a legal opinion regarding the validity of the 2036 Notes, attached as Exhibit 5.1 to this Form 8-K and incorporated by reference herein and into the Registration Statement.
