Quantum-Si Announces the Release of Two New Manuscripts Demonstrating the Value of Single-Molecule Protein Sequencing in Clinical Proteomics and Pathogen & Toxin Detection<\/b><\/p>\n

BRANFORD, Conn.–(BUSINESS WIRE<\/a>)–Quantum-Si Incorporated<\/a> (Nasdaq: QSI) (\u201cQuantum-Si,\u201d \u201cQSI\u201d or the \u201cCompany\u201d), a proteomics technology company redefining protein analysis through single-molecule detection, today announced two new manuscripts have been released, one as a peer reviewed publication in the Journal of Analytical Chemistry and one via preprint on ChemRxiv. The preprint has also been submitted for peer review.<\/p>\n

\nIn the first paper, titled \u201cExploration of Semiconductor Chip-Based Single-Molecule Protein Sequencing for Identification of Hemoglobin Variants\u201d, the authors demonstrate the ability of Quantum-Si\u2019s protein sequencing technology to directly identify clinically relevant hemoglobin variants from blood samples that are difficult to detect by traditional methods. The authors concluded that as the sequencing coverage increases, Quantum-Si\u2019s protein sequencing technology will be well positioned as a tool in clinical proteomics and hemoglobinopathy research.<\/p>\n

\n\u201cWe are excited to see Dr. Luo\u2019s hemoglobin variant paper be published by the Journal of Analytical Chemistry\u201d, said Jeff Hawkins, President and Chief Executive Officer of Quantum-Si. \u201cThis paper does an excellent job showcasing the promise of our technology to extend beyond basic research and into the field of clinical proteomics, to be applied to address complex conditions like hemoglobinopathies that are not easily resolved using current technologies.\u201d<\/p>\n

\nIn the second manuscript, released via preprint on ChemRxiv and titled \u201cOptimization of Quantum-Si Platinum single-molecule protein sequencing platform towards improved complex-matrix protein identification\u201d, the authors from the U.S. Naval Research Laboratory described a modified workflow to enable biological sample to result in under 24 hours. Furthermore, they demonstrated that this modified workflow could successfully identify long single-domain antibodies, shorter protein toxoids and detect proteins of interests from complex mixtures. Notably, the authors state that Quantum-Si currently presents the only benchtop, commercialized, single-molecule protein sequencing approach that eliminates arduous procedures typically associated with traditional methods.<\/p>\n

\n\u201cWe are excited to see the results presented in the manuscript from the U.S. Naval Research Laboratory demonstrating a biological sample to result workflow in under 24 hours\u201d, said Hawkins. \u201cWe appreciate the challenges of applying new technologies to complex real world problems like pathogens and toxin detection and look forward to continuing to support the U.S. Naval Research Laboratory in their endeavors.\u201d<\/p>\n

\nHawkins continued, \u201cThese two papers are just a part of a strong pipeline of studies that we expect to be released during 2026. These papers demonstrate that the potential opportunity for our technology extends well beyond the basic research markets we operate in today with our first-generation technology. We believe that these studies also serve as additional data points that our Proteus platform strategy is well aligned with what the market needs to be able to fully realize the benefits of our proprietary single-molecule protein sequencing technology.\u201d<\/p>\n

These forward-looking statements include, without limitation, the Company\u2019s expectations with respect to future performance and development and commercialization of products and services, its anticipated cash runway, anticipated data and product launches (including Proteus), investor confidence in Quantum-Si and our strategic roadmap, and any financial guidance. These forward-looking statements involve significant risks and uncertainties that could cause the actual results to differ materially from those discussed in the forward-looking statements. Most of these factors are outside the Company\u2019s control and are difficult to predict. Factors that may cause such differences include, but are not limited to: the inability to maintain the listing of the Company\u2019s Class A common stock on The Nasdaq Stock Market; the ability of the Company to grow and manage growth and retain its key employees; the Company\u2019s ongoing leadership transitions and succession planning; changes in applicable laws or regulations; the ability of the Company to raise financing in the future; the success, cost and timing of the Company\u2019s product development and commercialization activities, including the use and benefit of artificial intelligence in these and other activities; the commercialization and adoption of the Company\u2019s existing products and the success of any product the Company may offer in the future; the potential attributes and benefits of the Company\u2019s commercialized Platinum protein sequencing instruments and kits and the Company\u2019s other products (including Proteus) once commercialized; the Company\u2019s ability to obtain and maintain regulatory approval for its products, and any related restrictions and limitations of any approved product; the Company\u2019s ability to identify, in-license or acquire additional technology; the Company\u2019s ability to maintain its existing lease, license, manufacture and supply agreements; the Company\u2019s ability to compete with other companies currently marketing or engaged in the development or commercialization of products and services that serve customers engaged in proteomic analysis, many of which have greater financial and marketing resources than the Company; the size and growth potential of the markets for the Company\u2019s products and services, and its ability to serve those markets once commercialized, either alone or in partnership with others; the Company\u2019s estimates regarding future expenses, future revenue, capital requirements and needs for additional financing; the Company\u2019s financial performance; the Company’s defense and initiation of litigation matters; and other risks and uncertainties described under \u201cRisk Factors\u201d in the Company\u2019s most recent Annual Report on Form 10-K and Quarterly Reports on Form 10-Q and in the Company\u2019s other filings with the SEC.
