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 dependence of MSG Sports on revenues from its NBA and NHL sports teams generally means 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 sports teams’ games are played.

Use of Estimates	Use of Estimates The preparation of the accompanying Financial Statements in conformity with GAAP requires management to make estimates and assumptions about future events.

Such estimates include the valuation of accounts receivable, other current assets, goodwill, intangible assets, other long-lived assets, fair value of investments, deferred tax valuation allowance, tax accruals, and other liabilities. In addition, estimates are used in revenue recognition, revenue sharing expense (net of escrow and excluding playoffs), luxury tax expense, income tax expense (benefit), performance and share-based compensation, depreciation and amortization, litigation matters and other matters.

Fair Value Measurement	The fair value of the Company’s investments in common stock of Xtract One and other investments held in trust are determined based on quoted market prices in active markets, which are classified within Level I of the fair value hierarchy.
Valuation of Warrants	The Company’s Level III assets consist of warrants entitling the Company to acquire additional common stock of Xtract One. The Company’s warrants are included within Investments in the accompanying consolidated balance sheets.

The accompanying unaudited consolidated interim financial statements (referred to as the “Financial Statements” herein) have been prepared in accordance with U.S. generally accepted accounting principles (“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, 2024 (“fiscal year 2024”).

Principles of Consolidation

The consolidated financial statements of the Company include the accounts of Madison Square Garden Sports Corp. and its subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation.

Use of Estimates

The preparation of the accompanying Financial Statements in conformity with GAAP requires management to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenues and expenses. Such estimates include the valuation of accounts receivable, other current assets, goodwill, intangible assets, other long-lived assets, fair value of investments, deferred tax valuation allowance, tax accruals, and other liabilities. In addition, estimates are used in revenue recognition, revenue sharing expense (net of escrow and excluding playoffs), luxury tax expense, income tax expense (benefit), performance and share-based compensation, depreciation and amortization, litigation matters and other matters. Management believes its use of estimates in the Financial Statements to be reasonable.

Management evaluates its estimates on an ongoing basis using historical experience and other factors, including the general economic environment and actions it may take in the future. The Company adjusts such estimates when facts and circumstances dictate. However, these estimates may involve significant uncertainties and judgments and cannot be determined with precision. In addition, these estimates are based on management’s best judgment at a point in time and, as such, these estimates may ultimately differ from actual results. Changes in estimates resulting from weakness in the economic environment or other factors beyond the Company’s control could be material and would be reflected in the Company’s financial statements in future periods.
