**Item 1. Security and Issuer**

**(a) Title of Class of Securities:**
Class A Common Stock, par value $.01 per share

**(b) Name of Issuer:**
Sphere Entertainment Co.

**(c) Address of Issuer's Principal Executive Offices:**
TWO PENNSYLVANIA PLAZA, NEW YORK, NY, 10121

This Amendment No. 8 to Schedule 13D ("Amendment No. 8") is being filed jointly by (i) the individuals (in their individual capacity and/or as trustee or co-trustee of specified trusts) and trusts listed in Item 2(a) below (the "Group Members") who may be deemed to beneficially own all of the shares of Class B Common Stock, par value $0.01 per share (the "Class B Common Stock"), of Sphere Entertainment Co. (the "Issuer"), which shares of Class B Common Stock are convertible share for share at the option of the holder into Class A Common Stock of the Issuer, par value $0.01 per share (the "Class A Common Stock," and together with the Class B Common Stock, the "Common Stock"), and a certain number of shares of Class A Common Stock, in each case as described herein, and (ii) certain trustees of such Group Members (the persons referred to in clauses (i) and (ii) collectively, the "Reporting Persons") to report, among other things, the inclusion of Thomas C. Dolan as a Reporting Person.

The Schedule 13D filed by the original Reporting Persons on April 24, 2020, as amended and supplemented by Amendment No. 1 filed on March 30, 2021, Amendment No. 2 filed on July 14, 2021, Amendment No. 3 filed on March 1, 2024, Amendment No. 4 filed on December 31, 2024, Amendment No. 5 filed on February 4, 2025, Amendment No. 6 filed on September 10, 2025 and, for the Reporting Persons other than Thomas C. Dolan, Amendment No. 7 filed on February 27, 2026 (as amended, the "Schedule 13D"), is hereby amended and supplemented as set forth below in this Amendment No. 8.

**Item 5. Interest in Securities of the Issuer**

**(a)**
The disclosure in Item 5(a) and (b) is hereby amended and supplemented as follows:

(a) and (b) As of March 9, 2026, the Group Members may be deemed to beneficially own an aggregate of 8,698,719 shares of Class A Common Stock as a result of their beneficial ownership of (i) 1,831,965 shares of Class A Common Stock (inclusive of exercisable options, restricted stock units vesting within 60 days of the date hereof and shares held by the Dolan Family Foundation, for which certain Group Members serve as director), and (ii) 6,866,754 shares of Class A Common Stock issuable upon conversion of an equal number of shares of Class B Common Stock. This aggregate amount represents approximately 24.4% of the total shares of Common Stock deemed to be currently outstanding. Group Members in the aggregate may be deemed to have the current shared power to vote or direct the vote of and to dispose of or direct the disposition of 6,866,754 shares of Class A Common Stock issuable upon conversion of an equal number of shares of Class B Common Stock (representing all outstanding Class B Common Stock) because of the terms of the Class B Stockholders' Agreement (as previously defined in the Schedule 13D). Reporting Persons and individuals who are not Group Members but are trustees of trusts that are Group Members may be deemed to beneficially own an additional 58,744 shares of Class A Common Stock. Each of the Reporting Persons disclaims beneficial ownership of the securities held by the other Reporting Persons, and this report shall not be deemed to be an admission that any such person is the beneficial owner of such securities.

The percentages used herein with respect to the ownership of Class A Common Stock are calculated based on 28,635,366 outstanding shares of Class A Common Stock as of January 31, 2026, as reported by the Issuer in its Annual Report on Form 10-K that was filed with the SEC on February 12, 2026.

See the responses to Items 7 through 13 of each cover page to this Amendment No. 8, which are incorporated by reference. See Exhibit A for supplemental information regarding the beneficial ownership of Class A Common Stock by the Group Members and other individuals who are not Group Members but are trustees of trusts that are Group Members. See Exhibit B for additional information regarding the Reporting Persons that are trusts.

**(b)**
See Item 5(a) above, Exhibit A and Exhibit B.

**(c)**
There were no transactions in the Class A Common Stock effected by the Reporting Persons named in response to Item 5(a) since Amendment No. 7 to Schedule 13D.
