Opened in October 2021 Note: All references to Adjusted EBITDA in this document are based on our revised methodology as of September 2021. Adjusted EBITDA methodology prior to September 2021 utilized Non-GAAP rent (which accounted for the benefit of rent abatement in the period in which it was received) and Non-GAAP Other Operating Expenses included the benefit of Capex Allowance in the period in which was received.
