        <footnote id="F1">Relates to the spin-off of Madison Square Garden Entertainment Corp. (formerly MSG Entertainment Spinco, Inc., and referred to herein as &quot;MSGE&quot;) from Madison Square Garden Sports Corp. (formerly The Madison Square Garden Company, and referred to herein as &quot;MSGS&quot;), which occurred on April 17, 2020. To effect the spin-off, the issued and outstanding common stock of MSGE of 1,000 shares of common stock was recapitalized into 19,461,991 shares of MSGE's Class A common stock and 4,529,517 shares of MSGE's Class B common stock in a transaction exempt under Rule 16b-7. MSGS distributed all of the outstanding MSGE common stock to its stockholders (the &quot;Distribution&quot;) in a transaction exempt under Rule 16a-9. As a result of the Distribution, MSGS no longer beneficially owns any shares of MSGE and consequently is no longer subject to the requirements of Section 16 of the the Securities Exchange Act of 1934, as amended (the &quot;Exchange Act&quot;) with respect to MSGE.</footnote>
