~~Note Regarding Forward-Looking Statements~~ 2

Statements and other information included in this Current Report on Form 8-K that are not historical facts, including statements about the Company’s plans, strategies, beliefs and expectations, may constitute forward-looking statements. Forward-looking statements are subject to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995, as amended. Forward-looking statements speak only as of the date they are made and, except for the Company’s ongoing obligations under the U.S. federal securities laws, the Company undertakes no obligation to publicly update any forward-looking statement.

Forward-looking statements are subject to known and unknown risks and uncertainties and are based on estimates and assumptions that are subject to change or revision, including the anticipated progress towards completion of Sphere Abu Dhabi, that could cause actual results to differ materially from those expected or implied by the forward-looking statements or the estimates or assumptions used. Actual results may differ materially from those referred to in the forward-looking statements due to a number of important factors, including, without limitation, the failure to obtain governmental and regulatory approvals required for the construction and development of Sphere Abu Dhabi or other Sphere venues in the Exclusive Region; unexpected costs, liabilities or delays in connection with or with respect to the development, construction and operation of Sphere Abu Dhabi or other Sphere venues in the Exclusive Region, including but not limited to changes due to general economic, political and business conditions; potential legal proceedings relating to Sphere Abu Dhabi or other Sphere venues in the Exclusive Region and the outcome of any such legal proceeding; and other risks relating to the performance of the Agreements, including the risk that the potential benefits of the Agreements are not obtained within the expected time period or at all. Additional factors that may affect the Company’s future results are identified in the Company’s most recently filed Transition Report on Form 10-KT, subsequent Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other filings with the Securities and Exchange Commission (the “SEC”), which are available on the SEC’s website at www.sec.gov. Factors other than those listed above also could cause the Company’s results to differ materially from expected results.
