Nature of the Organization and Business	Note 1. Nature of the Organization and Business Corporate History Quantum Computing Inc. (“QCi,” the “Company” or “us”) was formed in the State of Nevada on July 25, 2001, under its original name, Ticketcart, Inc., which was changed to Innovative Beverage Group Holdings, Inc. in 2009. 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. (“QPhoton”) (the “QPhoton Merger”), a developer of quantum photonic systems and related technologies and applications. The QPhoton Merger enabled us to develop hardware applications integrated with the Company’s software platform, Qatalyst, that existed before the QPhoton Merger. In February 2026, the Company completed its acquisition of Luminar Semiconductor, Inc. (“LSI”), a manufacturer and seller of photonic components that are important building blocks on QCi’s technology roadmap. The LSI acquisition will bring QCi a portfolio of core photonic technologies, patents, and a highly experienced team of engineers and scientists that will accelerate QCi’s roadmap while continuing to support and grow LSI’s established customer base. In March 2026, the Company acquired NuCrypt, LLC (“NuCrypt”), a quantum communications technology company. NuCrypt contributes expertise in generating, distributing, and measuring entangled photons over fiber optic links, which is expected to enhance QCi’s development of quantum security products. The NuCrypt acquisition helps establish quantum communications as an important commercialization vertical within QCi’s broader quantum technology strategy.

Nature of Business QCi is an American company utilizing integrated photonics and non-linear quantum optics to develop and deliver machines for quantum computing, reservoir computing, and remote sensing, imaging and cybersecurity applications based on patented and proprietary photonics technology.
