Much of the demand is coming via the company’s experiences business, which includes On Location, acquired in January of 2020 just before the pandemic began impacting events.

Note Regarding Non-GAAP Financial Measures

This press release includes financial measures that are not calculated in accordance with under United States generally accepted accounting principles (“GAAP”), including Adjusted EBITDA, Adjusted EBITDA Margin and Adjusted Net Income.

Adjusted EBITDA is a non-GAAP financial measure and is defined as net income (loss), excluding income taxes, net interest expense, depreciation and amortization, equity-based compensation, merger, acquisition and earn-out costs, certain legal costs, restructuring, severance and impairment charges, certain non-cash fair value adjustments, certain equity earnings, COVID-19 related expenses, and certain other items when applicable. Adjusted EBITDA margin is a non-GAAP financial measure defined as Adjusted EBITDA divided by Revenue.

Management believes that Adjusted EBITDA is useful to investors as it eliminates the significant level of non-cash depreciation and amortization expense that results from our capital investments and intangible assets recognized in business combinations, and improves comparability by eliminating the significant level of interest expense associated with our debt facilities, as well as income taxes, which may not be comparable with other companies based on our tax structure.

Adjusted EBITDA and Adjusted EBITDA margin are used as the primary bases to evaluate our consolidated operating performance.

Adjusted Net Income is a non-GAAP financial measure and is defined as net income (loss) attributable to Endeavor Operating Company adjusted to exclude our share (excluding those relating to non-controlling interests) of the adjustments used to calculate Adjusted EBITDA, other than income taxes, net interest expense and depreciation, on an after-tax basis, the release of tax valuation allowances and other tax items

Adjusted Net Income adjusts income or loss attributable to the Company for items that are not considered to be reflective of our operating performance. Management believes that such non-GAAP information is useful to investors and analysts as it provides a better understanding of the performance of our operations for the periods presented and, accordingly, facilitates the development of future projections and earnings growth prospects.

Adjusted EBITDA, Adjusted EBITDA margin, and Adjusted Net Income have limitations as analytical tools, and you should not consider them in isolation or as a substitute for analysis of our results as reported under GAAP. Some of these limitations are:

7

We compensate for these limitations by using Adjusted EBITDA, Adjusted EBITDA margin and Adjusted Net Income along with other comparative tools, together with GAAP measurements, to assist in the evaluation of operating performance.

Adjusted EBITDA, Adjusted EBITDA margin and Adjusted Net Income should not be considered substitutes for the reported results prepared in accordance with GAAP and should not be considered in isolation or as alternatives to net income (loss), as indicators of our financial performance, as measures of discretionary cash available to us to invest in the growth of our business or as measures of cash that will be available to us to meet our obligations. Although we use Adjusted EBITDA, Adjusted EBITDA margin and Adjusted Net Income as financial measures to assess the performance of our business, such use is limited because it does not include certain material costs necessary to operate our business. Our presentation of Adjusted EBITDA, Adjusted EBITDA Margin and Adjusted Net Income should not be construed as indications that our future results will be unaffected by unusual or nonrecurring items. These non-GAAP financial measures, as determined and presented by us, may not be comparable to related or similarly titled measures reported by other companies.

Set forth below are reconciliations of our most directly comparable financial measures calculated in accordance with GAAP to these non-GAAP financial measures on a consolidated basis.

A reconciliation of the Company’s Adjusted EBITDA guidance to the most directly comparable GAAP financial measure cannot be provided without unreasonable efforts and is not provided herein because of the inherent difficulty in forecasting and quantifying certain amounts that are necessary for such reconciliations, including adjustments that are made for equity-based compensation expense, restructuring charges, gains, losses and impairments related to acquisitions and divestitures of businesses, non-cash fair value adjustments of embedded foreign currency derivatives, equity method earnings or losses and fair value adjustments for investments, certain tax items and other adjustments reflected in our reconciliation of historical Adjusted EBITDA, the amounts of which, could be material.
