NON-GAAP FINANCIAL MEASURES
Certain financial measures used in this Press Release are not defined by U.S. generally accepted accounting
principles (“GAAP”) and as such are considered non-GAAP financial measures. We provide these measures toenhance the user’s overall understanding of the Company’s current financial performance and the Company’s
prospects for the future. Investors are cautioned that these non-GAAP financial measures may not be defined in thesame manner by other companies and, as a result, may not be comparable to other similarly titled measures usedby other companies. Also, these non-GAAP financial measures should not be construed as alternatives, or superior,
to other measures determined in accordance with GAAP. The non-GAAP financial measures used in this Press
Release are defined below.
Adjusted EBITDA and Adjusted EBITDA Margin: Represents GAAP net income (loss) adjusted for: (i) interest
expense, net; (ii) tax provision (benefit); (iii) gain on event cancellation insurance claims, as applicable; (iv) gain/loss
on divestitures, as applicable; (v) other (income) expense, net; (vi) stock-based compensation expense; (vii)
depreciation, amortization, and accretion; (viii) loss on impairment of lease related assets, as applicable; and (ix)acquisition and integration charges and certain other non-recurring items. Adjusted EBITDA Margin represents
Adjusted EBITDA divided by GAAP Revenue. We believe Adjusted EBITDA and Adjusted EBITDA Margin areimportant measures of our recurring operations as they exclude items not representative of our core operating
results.
Adjusted Net Income: Represents GAAP net income (loss) adjusted for the impact of certain items directly related
to acquisitions and other non-recurring items. These adjustments include: (i) the amortization of acquired
intangibles; (ii) acquisition and integration charges and other non-recurring items; (iii) gain on event cancellation
insurance claims, as applicable; (iv) gain/loss on divestitures, as applicable; (v) loss on impairment of lease related
assets, as applicable; (vi) the non-cash (gain) loss on de-designated interest rate swaps, as applicable; and (vii) therelated tax effect. We believe Adjusted Net Income is an important measure of our recurring operations as it
excludes items that may not be indicative of our core operating results.
Adjusted EPS: Represents GAAP diluted EPS adjusted for the impact of certain items directly related toacquisitions and other non-recurring items. These adjustments include on a per share basis: (i) the amortization ofacquired intangibles; (ii) acquisition and integration charges and other non-recurring items; (iii) gain on event
cancellation insurance claims, as applicable; (iv) gain/loss on divestitures, as applicable; (v) loss on impairment oflease related assets, as applicable; (vi) the non-cash (gain) loss on de-designated interest rate swaps, asapplicable; and (vii) the related tax effect. We believe Adjusted EPS is an important measure of our recurring
operations as it excludes items that may not be indicative of our core operating results.
Free Cash Flow: Represents cash provided by operating activities determined in accordance with GAAP lesspayments for capital expenditures. We believe Free Cash Flow is an important measure of the recurring cash
generated by the Company’s core operations that may be available to be used to repay debt obligations,repurchase our stock, invest in future growth through new business development activities, or make acquisitions.
Foreign Currency Neutral (FX Neutral): We provide foreign currency neutral dollar amounts and percentages forour contract values, revenues, certain expenses, and other metrics. These foreign currency neutral dollar amounts
and percentages eliminate the effects of exchange rate fluctuations and thus provide a more accurate andmeaningful trend in the underlying data being measured. We calculate foreign currency neutral dollar amounts byconverting the underlying amounts in local currency for different periods into U.S. dollars by applying the same
foreign exchange rates to all periods presented.
