Item 1.01. Entry Into Material Definitive Agreement. On June 26, 2026, VeriSign, Inc. (the “Company”) completed a registered offering (the “Offering”) of $550 million aggregate principal amount of the Company’s 5.100% Senior Notes due 2031 (the “Notes”). The Offering has been registered under the Securities Act of 1933, as amended (the “Securities Act”), pursuant to a registration statement on Form S-3 (Registration No. 333-285483) of the Company (the “Registration Statement”), and the prospectus supplement dated June 18, 2026 and filed with the Securities and Exchange Commission pursuant to Rule 424(b) of the Securities Act on June 23, 2026 (the “Prospectus Supplement”). The Notes were issued pursuant to the Indenture (the “Base Indenture”), dated as of June 8, 2021, between the Company and U.S. Bank Trust Company, National Association (as successor in interest to U.S. Bank National Association), as trustee (the “Trustee”), as supplemented by the Third Supplemental Indenture (the “Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), dated as of June 26, 2026, between the Company and the Trustee. The Notes are represented by two global notes, a form of which is included as an exhibit to the Supplemental Indenture. The Notes accrue interest at a rate per annum equal to 5.100% and will mature on July 15, 2031 unless redeemed or repurchased prior to that date. Interest on the Notes will be payable semi-annually in cash in arrears on January 15 and July 15 of each year, commencing January 15, 2027. The Notes are the Company’s senior unsecured obligations and rank equally in right of payment with all of its other senior indebtedness and senior to all of its future indebtedness that is expressly subordinated in right of payment to the Notes. The Indenture contains covenants that, among other things, restrict the Company’s ability and the ability of certain of its subsidiaries to create or assume liens, enter into sale and leaseback transactions, and restrict the Company’s ability to engage in mergers or consolidations or sell, lease or transfer all or substantially all of its property and assets, subject in each case to certain qualifications and exceptions. Under the Indenture, the Company is required to offer to repurchase the Notes at a price equal to 101% of their principal amount, plus accrued and unpaid interest, upon the occurrence of a change of control repurchase event. The Indenture includes customary events of default, including payment defaults and certain events of bankruptcy, insolvency, or reorganization. Under the Indenture, the Company may redeem some or all of the Notes at any time or from time to time prior to June 15, 2031 at a specified “make-whole” premium described in the Indenture. The Company also has the option at any time or from time to time on or after June 15, 2031 to 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 thereon to the redemption date, as more fully described in the Indenture.
