Industry Context

The proteomics market is identified as large and growing, valued at over $75 billion, driven by the increasing need for deep proteoform-level analysis in academic research, pharmaceutical development, biotechnology, and clinical diagnostics. Current industry platforms are often characterized by high capital costs and complex, manual workflows, which limit broader adoption. Quantum-Si's Proteus platform aims to disrupt this landscape by offering an affordable, automated, and high-throughput solution, directly addressing the unmet need for comprehensive PTM and proteoform analysis, which is critical for understanding disease mechanisms and identifying therapeutic targets.

Comparison to Industry Standards

• Current specialized proteomics platforms often cost $1 million or more each, limiting adoption to core labs, whereas Proteus is designed to be affordable, enabling 'any lab, anywhere' to perform proteomics.
• Existing technologies face technical tradeoffs between the breadth of protein coverage and the depth of insights, a limitation Proteus seeks to overcome with single-molecule protein sequencing for broad PTM coverage and protein-agnostic analysis.
• Manual laboratory and data analysis workflows of current proteomics solutions restrict the number of laboratories capable of performing advanced proteomics, while Proteus's automation dramatically simplifies the workflow and increases throughput.
• Affinity-based methods cannot scale to the complexity required for complete proteome coverage, which would necessitate tens of thousands or more unique, site-specific affinity reagents; single-molecule protein sequencing is designed to tackle this complexity.

Stakeholder Impact

• Shareholders: Potential for increased shareholder value through successful product development and market penetration of the Proteus platform, supported by a strong cash runway and clear strategic roadmap.
• Customers (Researchers, Pharma/Biotech): Access to a more affordable, automated, and high-throughput protein sequencing technology (Proteus) capable of deeper proteoform analysis, addressing current limitations in the field.
• Employees: Continued focus on R&D and product development, potentially leading to growth in employment opportunities and professional development within the company.
• Partners: Opportunities for collaboration in commercialization, product development, and manufacturing, as the company aims to build a robust partner ecosystem.
• Creditors: The company's strong cash runway into Q2 2028 indicates a stable financial position, potentially reducing credit risk.

Next Steps

• Fully integrated Proteus systems are expected to be delivered and operational in Q1 2026.
• End-to-end sequencing on fully integrated Proteus systems is planned for Q2 2026.
• The instrument list price for Proteus is scheduled to be released in Q2 2026.
• A Platinum upgrade program is set to be released in Q3 2026.
• Proteus launch capabilities are expected to be released in Q3 2026.
• Internal verification and validation (V&V) for Proteus is slated for Q4 2026.
• The official launch of the Proteus platform is targeted for Q4 2026.
• The company plans to extend its technology lead through best-in-class R&D innovation and execution.
• Building a partner ecosystem to accelerate application development and deliver sample-to-report workflows is a key strategic objective.
• Growing the user base with Platinum Pro and developing the market for the Proteus launch are ongoing priorities.
