Effective July 20, 2018, the trading symbol for the Company’s common stock, par value $0.0001, on the OTC Market changed from “IBGH” to “QUBT”.

As of September 30, 2024, the Company also had an accumulated deficit of $149.2 million and working capital of $1.5 million. Furthermore, we have not achieved a level of sales adequate to support the Company’s cost structure and may need to raise additional funds in the next 12 months by selling additional equity or incurring debt. It is management’s opinion that these conditions raise substantial doubt about our ability to continue as a going concern.</p>

The term of these indemnification agreements is generally perpetual any time after the execution of the agreement. The maximum potential amount of future payments we could be required to make under these agreements is not determinable.

These agreements also require us to advance their expenses incurred as a result of any proceeding against them as to which they could be indemnified and to make good faith determination whether or not it is practicable for us to obtain directors and officers insurance.

In general, management believes that ordinary course of business matters will not have a material adverse effect on our consolidated financial position or results of operations and are adequately covered by our liability insurance. However, it is possible that condensed consolidated cash flows or results of operations could be materially affected in any particular period by the unfavorable resolution of one of more of these contingencies or because of the diversion of management’s attention and the incurrence of significant expenses.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"> </p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">See Part II, Item 1, <i>Legal Proceedings</i>, in this Form 10-Q for additional details on the status of motions on the following proceedings.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><span style="text-decoration:underline">BV Advisory v.

Accordingly, 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 September 30, 2024 and December 31, 2023.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">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.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><span style="text-decoration:underline">BV Advisory v.

BV Advisory rejected the Merger Consideration (as defined below) 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.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">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 (as defined below). 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 QPhoton Merger).</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Accordingly, as of September 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 September 30, 2024 and 2023, and the Unissued QPhoton Warrants have no carrying value as a liability on the Company’s condensed consolidated balance sheet as of September 30, 2024.</p>
