8 US GAAP to Non - GAAP Reconciliation (1) Reconciling items to Adjusted EBITDA and Adjusted Net Income (Loss) are not typically forecasted by the Company based on thei r n ature as being primarily driven by transactions that are not part of the core operations of the business and, as a result, cannot be estimated without unreasonable cost or uncertainty. As such, for the f ore casted full year ended December 31, 2024, we have only included known reconciling items incurred through the nine months ended September 30, 2024. We have not included forecasted amounts for the rem ainder of 2024, or for the forecasted full year ended December 31, 2025. NOTE: For definitions of non - GAAP measures as well as descriptions of current period reconciling items from Net Income (Loss) to Adjusted EBITDA and to Adjusted Net Income (Loss), refer to the press release furnished as Exhibit 99.1 to our Form 8 - K dated November 6, 2024. Totals may not sum due to rounding.
