Charter and Cox Unify Debt Guarantee Structure After Transaction Close

Charter Communications, Inc. (NASDAQ:CHTR), operating through its subsidiaries, disclosed the execution of multiple supplemental indentures and guarantee arrangements following the August 19, 2026 closing of its transaction with Cox Enterprises, Inc. The transaction, originally governed by an agreement dated May 16, 2025, involved Charter acquiring the commercial fiber and managed IT and cloud services businesses of Cox Communications, LLC, while Cox Enterprises contributed Cox Communications' residential cable business to Charter Communications Operating, LLC.

According to the filing, on August 24, 2026, certain Cox entities became guarantors under the Charter Credit Agreement - an Amended and Restated Credit Agreement originally dated March 18, 1999, most recently amended by Amendment No. 7 dated May 6, 2026 - and granted liens on substantially all of their assets and pledges of equity interests as collateral. The trustee and collateral agent for the CCO and Cox indentures is The Bank of New York Mellon Trust Company, N.A., while The Bank of New York Mellon serves as trustee under the TWC and TWCE indentures.

The filing further reported that existing guarantors of Charter's secured debt, including parties to the Charter Credit Agreement and the CCO, TWC, and TWCE indentures, have become guarantors of the Cox Indenture and granted liens on their collateral to secure obligations under that indenture. The result, as the filing states, is that obligations under all four indentures and the Charter Credit Agreement "are guaranteed and secured on a pari passu basis." Item 2.03 of the filing incorporates the Item 1.01 disclosures, noting the creation of direct financial obligations through the new guarantee arrangements.
