Sentiment and the balance of points
Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.

beneficial ownership financial
"change in the Reporting Persons’ beneficial ownership"
Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.
exercisable financial
"options ... are exercisable or will become exercisable within 60 days"
restricted stock units financial
"restricted stock units vesting within 60 days"
Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.
Class B Stockholders’ Agreement financial
"because of the terms of the Class B Stockholders’ Agreement"

Item 1 Comment:
This Amendment No. 9 to Schedule 13D ("Amendment No. 9") 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 a change in the Reporting Persons' beneficial ownership resulting from the options previously granted to Mr. James Dolan becoming exercisable. As of October 20, 2026, options underlying 1,415,602 shares of Class A Common Stock are exercisable or will become exercisable within 60 days.
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, for the Reporting Persons other than Thomas C. Dolan, Amendment No. 7 filed on February 27, 2026, and Amendment No. 8 filed on March 9, 2026 (as amended, the "Schedule 13D"), is hereby amended and supplemented as set forth below in this Amendment No. 9. | ||
| 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 October 20, 2026, the Group Members may be deemed to beneficially own an aggregate of 9,974,940 shares of Class A Common Stock as a result of their beneficial ownership of (i) 3,108,186 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 26.7% 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 58,594 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 29,046,853 outstanding shares of Class A Common Stock as of July 24, 2026, as reported by the Issuer in its Quarterly Report on Form 10-Q that was filed with the SEC on July 30, 2026.
See the responses to Items 7 through 13 of each cover page to this Amendment No. 9, 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. 8 to Schedule 13D. This Amendment No. 9 is being filed to report a change in the Reporting Persons' beneficial ownership resulting from the options previously granted to Mr. James Dolan becoming exercisable. As of October 20, 2026, options underlying 1,415,602 shares of Class A Common Stock are exercisable or will become exercisable within 60 days. | |
| Item 7. | Material to be Filed as Exhibits. | |
The disclosure in Item 7 is hereby amended by adding Exhibit A.4 and Exhibit D.4 in appropriate order as follows:
Exhibit A.4: Supplemental Beneficial Ownership Information
