Cogent Communications Holdings, Inc. Form 8-K Filing

Cogent Communications Holdings, Inc. (the "Company"), through its wholly-owned subsidiaries Cogent Communications Group, LLC and Cogent Finance, Inc., entered into a First Supplemental Indenture on June 15, 2026. This amendment to the existing Indenture, dated June 17, 2025, modifies several provisions concerning the 6.500% Senior Secured Notes due 2032. Key changes include increasing the secured leverage ratio under the "ratio liens" basket from 4.00:1.00 to 4.75:1.00. The amendment also mandates that proceeds from certain data center sales must be used to repurchase existing indebtedness at a discount, with at least 50% allocated to retiring the 6.500% Senior Secured Notes due 2032. Furthermore, the Supplemental Indenture restricts the use of data center sale proceeds for increasing restricted payment capacity and prohibits the transfer or refinancing of indefeasible rights of use (IRUs) by unrestricted subsidiaries or non-guarantor restricted subsidiaries, with limited exceptions. These changes follow the receipt of requisite consents from noteholders and are effective immediately upon execution.
