The Company has recorded an estimated payable (the “BV Advisory Payable”), recognized as other current liabilities on the unaudited condensed consolidated financial statements, based on best available information in the amount of $536 thousand as of June 30, 2024 and December 31, 2023.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">On August 16, 2022, BV Advisory filed a complaint in the Court of Chancery of the State of Delaware (the “DE Chancery Court”) naming the Company and certain of its directors and officers (among others) as defendants seeking, among other relief, monetary damages. The Company believes that BV Advisory’s claims have no merit and intends to defend itself vigorously. BV Advisory’s claims are not covered by the Company’s liability insurance, nor does the Company believe it is necessary to accrue an amount in addition to the BV Advisory Payable at this time.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"><span style="text-decoration:underline">BV Advisory v.

BV Advisory, rejected the Merger Consideration and on October 13, 2022, commenced litigation by filing a petition in the DE Chancery Court seeking appraisal rights on the shares of QPhoton it allegedly owned (which shares represented 10% of the shares of QPhoton outstanding immediately prior to the Company’s acquisition of QPhoton). The Company included BV Advisory’s purported ownership of QPhoton in the purchase price accounting for the QPhoton Merger.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">The Company’s total purchase price of QPhoton was approximately $71.0 million, or $69.9 million net of cash acquired, consisting of Company common stock, Series B Preferred Stock and QPhoton Warrants. While the total shares of the Company’s common stock on an as-converted basis offered in the QPhoton Merger was 36,600,823 (the “Merger Consideration”), the fair market valuation contemplated 31,299,417 of the shares, which assumed full conversion of the 2,377,028 shares of Series B Preferred Stock to common stock at the 10:1 ratio, and that only 1,726,931 of the warrants to purchase up to 7,028,337 shares of the Company’s common stock (the “QPhoton Warrants”) would eventually be exercised (specifically only the QPhoton Warrants for which the associated Company options and/or warrants had an exercise price at or below $2.27 at the time of the Transaction).</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">Accordingly, as of June 30, 2024 and 2023, the Company has neither issued 2,957,251 shares of the Company’s common stock on an as converted basis (the “Unissued QPhoton Shares”) nor 702,834 warrants to purchase shares of the Company’s common stock (the “Unissued QPhoton Warrants”) that were included in the Merger Consideration. The Unissued QPhoton Shares are included in the statement of stockholder’s equity as additional paid in capital as of as of June 30, 2024 and 2023, and the Unissued QPhoton Warrants have no carrying value as a liability on the Company’s consolidated balance sheet as of June 30, 2024.</span></p>
