(“QCi” or the “Company”) was formed in the State of Nevada on July 25, 2001, under its prior name, Ticketcart, Inc. The Company redomiciled to Delaware on February 22, 2018 and changed its name to Quantum Computing Inc. 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”. On July 15, 2021 the Company uplisted to The Nasdaq Stock Market LLC. On June 16, 2022, the Company merged with QPhoton, Inc.

The Company was founded in 2018 by leaders in supercomputing, mathematics, and computer programming to solve the enormous challenge with quantum computing in terms of the high cost and lengthy times required for quantum software development. While much of the market focuses on Quantum Processing Unit (QPU) hardware, the Company’s experts realized that the quantum marketplace and vendors were limiting access to quantum computers due to the complexity of programming them. At the present time, only a very limited number of highly specialized quantum experts are able to use software development toolkits (“SDKs”) to create these critical programs and applications. The Company’s flagship software solution, Qatalyst, has enabled subject matter experts (SMEs) to run existing software on quantum processing units without the need for specialized programming with SDKs. As a result of the merger with QPhoton in June 2022, the Company is now able to offer its software capability that is embedded within its new hardware offering of photonic quantum computing systems and related services.</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">Liquidity</span></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 October 28, 2022 the Company filed a shelf registration statement on Form S-3 under the Securities Act of 1933, as amended (the “Securities Act”), which was declared effective on November 8, 2022 (the “2022 shelf”). Under the 2022 Shelf at the time of effectiveness, the Company had the ability to raise up to $100 million by selling common stock, preferred stock, debt securities, warrants and units. On December 5, 2022, the Company entered into an At-the-Market Issuance Sales Agreement (the “ATM Agreement”) with Ascendiant Capital Markets, LLC (“Ascendiant”) relating to the sale of its common stock, and incorporated the ATM Agreement into the 2022 Shelf by amendment that was declared effective January 10, 2023. On August 17, 2023, the Company and Ascendiant entered into an amendment (the “ATM Amendment”) to the ATM Agreement, increasing the amount of Common Stock the Company may offer and sell via the “at the market” equity offering program from $25,000,000 to $50,000,000 (the “ATM Upsize”). Following the ATM Upsize, the Company is able to offer and sell shares of Common Stock having an aggregate offering price of up to $27,362,717 via the “at the market” equity offering program. The Company filed a prospectus supplement, dated August 18, 2023 with the Securities and Exchange Commission (the “SEC”) in connection with the offer and sale of the shares pursuant to the ATM Amendment (the “Prospectus Supplement”).</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">Under the terms of the ATM Agreement, as amended, the Company may, but is not obligated to, offer and sell, from time to time, shares of common stock having an aggregate offering price of up to $50 million through Ascendiant. Sales of common stock, if any, will be made by any method permitted that is deemed an “at the market offering” as defined in Rule 415 under the Securities Act. The Company intends to use any net proceeds from the sale of securities for our operations and for other general corporate purposes, including, but not limited to, capital expenditures, general working capital, and possible future acquisitions. There were 15,290,513 shares of common stock sold under the ATM Agreement during the nine months ended September 30, 2023 and no shares of common stock sold under the ATM Agreement during the nine months ended September 30, 2022. As of September 30, 2023, the Company has utilized $23.5 million of the 2022 Shelf. The Company has approximately $76.5 million available under the 2022 Shelf and $26.5 million available under the ATM Agreement, as amended, as of September 30, 2023.</p>
