_______________ (1)The pro forma column above gives effect to (i) the filing and effectiveness of our amended and restated certificate of incorporation, which will occur immediately prior to the completion of this offering; (ii) the Preferred Stock Conversion; (iii) the Option Exercise; (iv) the RSU Net Settlement; (v) the increase in accrued expenses and other current liabilities and an equivalent decrease in additional paid-in capital of $                in connection with the estimated tax withholding and remittance obligations related to the RSU Net Settlement; and (vi) stock-based compensation expense of approximately $               that we will recognize upon the completion of this offering related to RSUs subject to service-based and liquidity-based vesting conditions for which the service-based vesting condition was satisfied as of June 30, 2024 and for which the liquidity-based vesting condition will be satisfied in connection with this offering. (2)The pro forma as adjusted column above gives further effect to (i) the pro forma adjustments set forth above; (ii) the issuance and sale of                 shares of Class A common stock by us in this offering at an assumed initial public offering price of $           per share, which is the midpoint of the estimated price range set forth on the cover page of this prospectus, after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us; (iii) the receipt by us of gross proceeds of approximately $                in connection with the Option Exercise; and (iv) the use of a portion of the net proceeds from this offering to satisfy the estimated tax withholding and remittance obligations related to the RSU Net Settlement. (3)Each $1.00 increase or decrease in the assumed initial public offering price of $             per share, which is the midpoint of the estimated price range set forth on the cover page of this prospectus, would increase or decrease, as applicable, each of cash and cash equivalents, working capital, total assets, and stockholders’ deficit by $            , assuming that the number of shares of Class A common stock offered by us, as set forth on the cover page of this prospectus, remains the same, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us. Similarly, each increase or decrease of 1.0 million shares in the number of shares of Class A common stock offered by us would increase or decrease, as applicable, each of cash and cash equivalents, working capital, total assets, and stockholders’ deficit by $            , assuming the assumed initial public offering price of $             per share remains the same, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us. In addition, each 1.0% increase or decrease in the assumed tax withholding rate would increase or decrease, as applicable, the amount of estimated tax withholding and remittance obligations related to the RSU Net Settlement by $            . Pro forma adjustments in the footnotes above and the related information in the consolidated balance sheet data are illustrative only and will be adjusted based on the actual initial public offering price and other terms of this offering determined at pricing, the actual tax withholding rate, as well as the actual amount of RSUs settled in connection with this offering (including after accounting for forfeitures prior to the settlement date). (4)Working capital is defined as total current assets less total current liabilities. See our unaudited interim consolidated financial statements and the related notes thereto included elsewhere in this prospectus for further details regarding our current assets and current liabilities.

Non-GAAP Financial Measures We use certain non-GAAP financial measures to supplement the performance measures in our consolidated financial statements, which are presented in accordance with GAAP. These non-GAAP financial measures include non-GAAP operating loss and non-GAAP net loss. We use these non-GAAP financial measures for financial and operational decision-making and as a means to assist us in evaluating period-to-period comparisons. By excluding certain items that may not be indicative of our recurring core operating results, we believe that non-GAAP operating loss and non-GAAP net loss provide meaningful supplemental information regarding our performance. Accordingly, we believe these non-GAAP financial measures are useful to investors and others because they allow for additional information with respect to financial measures used by management in its financial and operational decision-making and they may be used by our institutional investors and the analyst community to help them analyze the health of our business. However, there are a number of limitations related to the use of non-GAAP financial measures, and these non-GAAP measures should be considered in addition to, not as a substitute for or in isolation from, our financial results prepared in accordance with GAAP. Other companies, including companies in our industry, may calculate these non-GAAP financial measures differently or not at all, which reduces their usefulness as comparative measures. Non-GAAP Operating Loss We define non-GAAP operating loss as operating loss presented in accordance with GAAP, adjusted to exclude stock-based compensation expenses. We have presented non-GAAP operating loss because we consider non-GAAP operating loss to be a useful metric for investors and other users of our financial information in evaluating our operating performance because it excludes the impact of stock-based compensation, a non-cash charge that can vary from period to period for reasons that are unrelated to our core operating performance. This metric also provides investors and other users of our financial information with an additional tool to compare business performance across companies and periods, while eliminating the effects of items that may vary for different companies for reasons unrelated to core operating performance. A reconciliation of our GAAP operating loss, the most directly comparable GAAP financial measure, to non-GAAP operating loss is presented below:

Non-GAAP Net Loss We monitor non-GAAP net loss for planning and performance measurement purposes. We define non-GAAP net loss as net loss reported on our consolidated statements of operations, excluding the impact of stock-based compensation expenses and change in fair value of forward contract liability. We have presented non-GAAP net loss because we believe that the exclusion of these charges allows for a more relevant comparison of our results of operations to other companies in our industry and facilitates period-to-period comparisons as it eliminates the effect of certain factors unrelated to our overall operating performance. Our calculation of non-GAAP net loss does not currently include the tax effects of the stock-based compensation expense adjustment because such tax effects have not been material to date.
