Quantum-Si Establishes Scientific Advisory Board to Shape Next-Generation Proteomic Technologies

Quantum-Si Incorporated (NASDAQ:QSI) ("Quantum-Si," "QSI" or the "Company"), The Protein Sequencing Company^™, announces the formation of its Scientific Advisory Board. Comprised of distinguished experts in proteomics, genomics, bioinformatics, chemistry, and engineering, the board will play a critical role in shaping Quantum-Si's scientific and development strategy, identifying emerging trends and applications, and strengthening engagement within the scientific community.

Dr. Gloria M. Sheynkman, a leading expert in proteoform characterization and single-molecule protein sequencing, has been named Chair of the Scientific Advisory Board. Dr. Sheynkman is an Assistant Professor at the University of Virginia with joint appointments in Molecular Physiology and Biological Physics, and Biochemistry and Molecular Genetics. Her research integrates advanced mass spectrometry, long-read RNA sequencing, and single-molecule protein sequencing to map and characterize diverse proteoforms, providing new insights into complex diseases such as cardiovascular disease and cancer. A recipient of numerous awards, she is actively involved in key professional organizations, including the American Society for Mass Spectrometry (ASMS) and the Human Proteome Organization (HUPO).

"Proteomics is entering a transformative era, and I'm thrilled to collaborate with Quantum-Si in advancing the tools needed to explore its full complexity. It is opening new doors for understanding proteoforms, complementing mass spectrometry and poised to reveal insights we previously couldn't access. I look forward to contributing to Quantum-Si's mission and driving innovation in the field," said Dr. Sheynkman.

"We are honored to welcome Dr. Sheynkman as Chair of our Scientific Advisory Board, along with an esteemed group of advisors who bring deep expertise in proteomics and single-molecule sequencing," said Jeff Hawkins, Chief Executive Officer of Quantum-Si. "Their guidance will be invaluable as we continue to advance proteomics through innovation in NGPS and beyond. As we expand our technology portfolio with Proteus™ and other future developments, their expertise will help guide us in unlocking new applications and broadening the impact of our solutions across life sciences."

Joining Dr. Sheynkman on the SAB are:

• Dr. Benjamin A. Garcia – A globally recognized leader in mass spectrometry-based proteomics, Dr. Garcia is the Raymond H. Wittcoff Distinguished Professor and Head of the Department of Biochemistry and Molecular Biophysics at Washington University School of Medicine in St. Louis. His research focuses on developing novel proteomic and bioinformatics approaches to study protein modifications and their role in epigenetic regulation and disease. He has published over 450 scientific papers and holds leadership positions in HUPO, US HUPO, ASMS, and the ACS.

• Dr. Bradley L. Pentelute – A Professor of Chemistry at Massachusetts Institute of Technology (MIT) and an Associate Member of the Broad Institute of Harvard and MIT, Dr. Pentelute's research explores peptide and protein synthesis, bioengineering, and molecular delivery systems. His expertise in chemical biology and peptide therapeutics brings a valuable perspective to Quantum-Si's efforts to expand protein sequencing applications.

• Dr. Denis Zaccarin – A seasoned expert in semiconductor technology and consumable development for sequencing platforms, Dr. Zaccarin previously held senior leadership positions at Pacific Biosciences of California (PacBio), including Senior Vice President of Research and Development. With extensive experience in engineering and optical systems, he will provide strategic insights into the development of Quantum-Si's next-generation technology.

The Scientific Advisory Board will support Quantum-Si in prioritizing key applications, fostering collaborations, and driving awareness of NGPS within the broader scientific community.
