(formerly Madison Square Garden Sports Corp. and referred to herein together with its subsidiaries, collectively, as “we,” “us,” “our,” “MSG Knicks,” or the “Company”), owns and operates one of the most storied franchises in all of professional sports, the New York Knickerbockers (“Knicks”) of the National Basketball Association (“NBA”) and, prior to the Rangers Distribution (as defined below), owned and operated the New York Rangers (“Rangers”) of the National Hockey League (“NHL”). Both the Knicks and the Rangers play their home games in Madison Square Garden Arena (“The Garden”). The Company also includes the Westchester Knicks of the NBA G League, and prior to the Rangers Distribution, the Hartford Wolf Pack of the American Hockey League. These professional sports franchises are collectively referred to herein as the “sports teams” or the “teams.” Prior to the Rangers Distribution, the Company also operated a professional sports team performance center — the Madison Square Garden Training Center in Greenburgh, NY. The Company operates and reports financial information in one segment. The Company’s decision to organize as one operating segment and report in one segment is based upon its internal organizational structure; the manner in which its operations are managed; and the criteria used by the Company’s Executive Chairman and Chief Executive Officer, its Chief Operating Decision Maker (“CODM”), to evaluate segment performance. The Company’s CODM reviews total company operating results to assess overall performance and allocate resources. The Company was originally incorporated in Delaware on March 4, 2015 as an indirect, wholly-owned subsidiary of MSG Networks Inc. (“MSG Networks”). All the outstanding common stock of the Company was distributed to MSG Networks stockholders (the “MSGS Distribution”) on September 30, 2015. On April 17, 2020, the Company distributed all of the outstanding common stock of Sphere Entertainment Co. (“Sphere Entertainment”) to its stockholders (the “Sphere Distribution”). On July 9, 2021, MSG Networks merged with a subsidiary of Sphere Entertainment and became a wholly-owned subsidiary of Sphere Entertainment. Accordingly, agreements between the Company and MSG Networks are now effectively agreements with Sphere Entertainment on a consolidated basis. On June 10, 2025, the Company completed its conversion from a corporation organized under the laws of the State of Delaware to a corporation organized under the laws of the State of Nevada. Unless the context otherwise requires, all references to Madison Square Garden Entertainment Corp. (“MSG Entertainment”), Sphere Entertainment and MSG Networks refer to such entity, together with its direct and indirect subsidiaries. Spin-off Transaction On October 26, 2026 (the “Distribution Date”), the Company distributed 100% of the outstanding common stock of MSG Rangers Corp. (“MSG Rangers”, formerly MSGS Spinco, Inc.) to its stockholders (the “Rangers Distribution”). MSG Rangers owns the New York Rangers business previously owned and operated by the Company. In the Rangers Distribution, stockholders of the Company received (a) one share of MSG Rangers’ Class A common stock, par value $0.01 per share, for every two shares of the Company’s Class A common stock, par value $0.01 per share (“Class A Common Stock”), held of record as of the close of business, New York City time, on October 20, 2026 (the “Record Date”), and (b) one share of MSG Rangers’ Class B common stock, par value $0.01 per share, for every two shares of the Company’s Class B common stock, par value $0.01 per share, held of record as of the close of business, New York City time, on the Record Date. In connection with the Rangers Distribution, the Company contributed $19,095 of cash to MSG Rangers. The accompanying unaudited consolidated interim financial statements include the financial results of the Company’s Rangers business in continuing operations for all periods presented. Beginning with the Company’s Quarterly Report on Form 10-Q for the quarterly period ending December 31, 2026, the historical financial results of the Rangers business through the Distribution Date will be presented as discontinued operations under U.S. generally accepted accounting principles (“GAAP”) for all periods presented. Basis of Presentation The accompanying unaudited consolidated interim financial statements (referred to as the “Financial Statements” herein) have been prepared in accordance with GAAP and Article 10 of Regulation S-X of the Securities and Exchange Commission for interim financial information, and should be read in conjunction with the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2026 (our “2026 Form 10-K”). Certain information and note disclosures normally included in the annual financial statements have been condensed or omitted from these Financial Statements. The Financial Statements presented in this Quarterly Report on Form 10-Q are unaudited; however, in the opinion of management, the Financial Statements reflect all adjustments, consisting solely of normal recurring adjustments, necessary for a fair presentation of the results for the interim periods presented. The results of operations for the periods presented are not necessarily indicative of the results that might be expected for future interim periods or for the full fiscal year. The Company’s dependence on revenues from the Knicks, and prior to the Rangers Distribution, the Rangers, generally means that it earns a disproportionate share of its revenues in the second and third quarters of the Company’s fiscal year, which is when the majority of the teams’ games are played.
