Risks

• The Symphony System is still under development and subject to further validation, regulatory review, and clearance.
• There can be no assurance regarding the timing or success of regulatory activities for the Symphony System.
• Actual results or events could differ materially from forward-looking statements due to known and unknown risks, uncertainties, and other factors, including market conditions.
• Risks discussed under Item 1A. Risk Factors in the company's Form 10-K for the fiscal year ended December 31, 2024, and in Part II, Item 1A, Risk Factors in its Quarterly Reports on Form 10-Q for the fiscal quarters ended March 31, 2025, June 30, 2025, and September 30, 2025.

Future Outlook

The company anticipates utilizing antibodies from its proprietary immunogen for ongoing development activities to support its intellectual property strategy. The Symphony System is expected to undergo further validation, regulatory review, and clearance, with the IL-6 Test for sepsis designed to provide rapid results.

Management Comments

• Bluejay Diagnostics has completed commercial-scale production of both polyclonal and monoclonal antibodies targeting interleukin-6 (IL-6), a biomarker relevant to inflammatory and critical-care applications.
• Both polyclonal and monoclonal antibodies met internal performance criteria, including reactivity, for use in Symphony cartridge manufacturing intended for clinical and potential future commercial applications.
• Based on current antibody inventory, Bluejay estimates that it has sufficient material to support production of more than nine million Symphony cartridges for clinical and commercial manufacturing purposes.
• The company has also established the capability to produce additional antibodies as needed.
• Symphony remains under development and subject to further validation, regulatory review, and clearance, and there can be no assurance regarding the timing or success of these activities.

Industry Context

Comparison to Industry Standards

• NA

Stakeholder Impact

• Shareholders: Positive signal of progress in product development, potentially increasing confidence in the company's ability to bring its product to market, but tempered by remaining regulatory hurdles.
• Customers (Medical Professionals): Potential for a new rapid sepsis diagnostic tool in the future, offering improved triage and treatment decisions.
• Employees: Validation of R&D and manufacturing efforts, potentially boosting morale and job security related to product advancement.
• Suppliers: Continued demand for raw materials and services related to antibody production and system development.

Next Steps

• Ongoing development activities utilizing proprietary immunogen antibodies to support intellectual property strategy.
• Further validation of the Symphony System.
• Regulatory review and clearance for the Symphony System.
• Potential commercialization of the Symphony System as a diagnostic product in the United States, pending FDA authorization.

Key Dates

Recommendation

While the completion of commercial-scale antibody production is a positive and necessary step, it is an expected milestone in the product development lifecycle rather than a definitive commercial launch or regulatory approval. Significant hurdles remain, including further validation and critical FDA clearance, which introduce considerable uncertainty regarding the timing and ultimate success of the Symphony System. Investors should hold, awaiting more definitive news on regulatory progress and market entry before making further investment decisions.
