Announces Release of Version 3 Sequencing Kit

Announces Two Additional Kit Launches Expected by End of 2024

BRANFORD, Conn. — (BUSINESS WIRE) — August 7, 2024 — Quantum-Si Incorporated (Nasdaq: QSI) (“Quantum-Si,” “QSI” or the “Company”), The Protein Sequencing Company™, today announced financial results for the second quarter ended June 30, 2024.

“I’m pleased with the progress that we made on the commercial ramp up of Platinum during the second quarter. We are seeing strong customer interest in the unique capabilities of Platinum, which was underscored by presentations at major scientific conferences over the last few months, including the American Society of Mass Spectrometry and the European Society for Human Genetics,” said Jeff Hawkins, President and Chief Executive Officer of Quantum-Si. “We are in the early stages of penetrating a large market opportunity in proteomics, as researchers seek a deeper understanding of the importance of protein sequences and identify high value applications of the technology.”

Hawkins continued, “Today, we also announce the launch of our version 3 sequencing kit. This new kit will continue to give customers deeper insights into an ever-expanding number of proteins, more peptides per protein and more amino acids per peptide. We remain laser-focused on delivering a compelling technology roadmap of enhancements to our hardware, software and chemistries and now expect to release a version 2 of our library prep kit as well as a barcoding application specific library prep kit by the end of 2024. We believe these innovations will continue to extend our leadership in protein sequencing. Finally, we added Chuck Kummeth as independent Chairman of our Board of Directors. We look forward to benefitting from the experience Chuck has gained through decades of leadership with leading life sciences tools companies like Bio-Techne and Thermo Fisher Scientific.”

Second Quarter 2024 Financial Results

For the second quarter of 2024, the Company recorded revenue of $622,000. Gross profit was $354,000 and gross margin was 57%. For the six months ended June 30, 2024, the Company recorded revenue of $1.1 million, gross profit of $623,000, and gross margin of 57%. The periodic gross margin rate is expected to be variable in the near term as the Company works through the initial stages of commercialization as well as the timing and mix of product sales between instruments and consumable kits.

Total operating expenses were $26.8 million in the second quarter of 2024, compared to $27.0 million for the same period in the prior year, and $50.4 million for the six months ended June 30, 2024, compared to $56.3 million for the same period in the prior year. Adjusted total operating expenses were $24.4 million in the second quarter of June 30, 2024, compared to $24.0 million for the same period in the prior year, and adjusted total operating expenses for the six months ended June 30, 2024 was $46.3 million compared to $48.7 million for the same period in the prior year. Driven by the Company’s 2023 initiative to enact operating changes to utilize capital in the most efficient manner while accelerating R&D innovation and delivering product enhancements to customers, the overall adjusted operating expenses included reductions in R&D and G&A spend, partially offset with increased spending for commercial operations. Overall, the Company has been able to reduce core areas of spend while accelerating R&D focus, efficiency, and delivery while still funding the Company’s full commercial launch of its Platinum^® instrument.

Net loss was $23.1 million in the second quarter of 2024, compared to a net loss of $25.6 million in the same period of the prior year, and a net loss of $42.6 million for the six months ended June 30, 2024, compared to a net loss of $49.2 million for the same period in the prior year.
