Estimates made by the Company include, but are not limited to, those related to the valuation of common stock prior to the Business Combination, valuation of awards under the Extraordinary Performance Award Program (the “EPA Program”), valuation of convertible preferred stock warrants, valuation of convertible preferred stock tranche liabilities, and valuation of Assumed Common Stock Warrants among others. The Company bases these estimates on historical experience and on various other assumptions that it believes are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying amounts of assets and liabilities that are not readily apparent from other sources. Actual results could differ materially from those estimates.</span><span style="color:rgba(0,0,0,1);white-space:pre-wrap;font-weight:normal;font-size:10.0pt;font-family:Times New Roman;"> </span></p>
