Vivid Seats believes that these non - GAAP measures of financial results (including on a fo rward - looking basis) provide useful supplemental information to investors about Vivid Seats. Vivid Seats’ management uses forward - looking non - GAAP measures to evaluate Vivid Seats’ projected f inancials and operating performance. However, there are a number of limitations related to the use of these non - GAAP measures an d their nearest GAAP equivalents, including that they exclude significant expenses that are required by GAAP to be recorded in Vivid Seats’ financial measures. In addition, other companie s m ay calculate non - GAAP measures differently, or may use other measures to calculate their financial performance, and therefore, V ivid Seats’ non - GAAP measures may not be directly comparable to similarly titled measures of other companies. Additionally, to the extent that forward - looking non - GAAP financial measures are p rovided, they are presented on a non - GAAP basis without reconciliations of such forward - looking non - GAAP measures due to the inh erent difficulty in forecasting and quantifying certain amounts that are necessary for such reconciliations.

These projections are for illustrative purposes only and should not be relied upon as being necessarily indicative of future results. In this presentation, certain of the above - mentioned projected information has been provided for purposes of providing comparisons with historical data. The assumptions and estimates underlying the prospective financial information are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the prospect ive financial information. Projections are inherently uncertain due to a number of factors outside of Horizon’s or Vivid Seats’ c on trol. While all financial projections, estimates and targets are necessarily speculative, Horizon and Vivid Seats believe that the preparation of prospective financial information involves increasingly hig her levels of uncertainty the further out the projection, estimate or target extends from the date of preparation.
