 RSNs offered hereby subsequently issued under the Senior Note Indenture will be treated as a single class for purposes under the Senior Note Indenture, including, without limitation, voting waivers and amendments.

The Company will not pay any additional amounts to holders of the RSNs in respect of any tax, assessment or governmental charge.

#### Ranking
The RSNs will be direct, unsecured and unsubordinated obligations of the Company ranking equally with all other unsecured and unsubordinated obligations of the Company from time to time outstanding.

Since the Company is a holding company, the right of the Company and, hence, the right of creditors of the Company (including holders of the RSNs) to participate in any distribution of the assets of any subsidiary of the Company, whether upon liquidation, reorganization or otherwise, is structurally subordinated to the claims of creditors and any preferred stockholders of each subsidiary. As of September 30, 2025, on a consolidated basis, the Company had approximately $72.6 billion principal amount of outstanding long-term debt (including securities due within one year), of which approximately $48.2 billion was long-term debt (including securities due within one year) of the Company’s subsidiaries. In addition, as of September 30, 2025, on a consolidated basis, the Company had approximately $0.1 billion principal amount of short-term notes payable, all of which billion was short-term notes payable of the Company’s subsidiaries. The RSNs will be effectively subordinated to all secured indebtedness of the Company. The Company had no secured debt outstanding at September 30, 2025.

There are no terms of the RSNs that limit the Company’s ability to incur additional indebtedness or that limit its subsidiaries’ ability to incur additional debt or other liabilities or issue preferred and preference stock.

The Series 2025C RSNs will mature on December 15, 2033 and will initially bear interest from the date of original issuance at a rate of % per annum. Subject to any changes to the interest payment dates made upon a successful remarketing, interest on each series of RSNs will be payable quarterly on March 15, June 15, September 15 and December 15 of each year (each, an “interest payment date”), comm
