Industry Context

This capital raise is a common strategic move for biotechnology and pharmaceutical companies like Rapport Therapeutics, which require substantial funding to advance their drug candidates through costly and lengthy clinical trial phases. Securing this level of financing indicates investor confidence in the company's pipeline, particularly RAP-219, and its long-term potential, despite the inherent risks of drug development.

Comparison to Industry Standards

• The filing does not provide specific details on comparable companies, projects, or results to allow for a detailed assessment against global benchmarks. However, public offerings are a standard method for biopharmaceutical companies to fund research and development, especially for clinical-stage assets like RAP-219. The offering size and pricing would typically be evaluated against recent similar-stage biotech offerings, but such data is not provided within this filing.

Stakeholder Impact

• Shareholders: Existing shareholders will experience dilution due to the issuance of new shares. However, the capital raise provides crucial funding for future growth and pipeline development, which could benefit long-term shareholder value.
• Employees: Continued funding for R&D and operations supports job security and potential growth opportunities within the company.
• Customers/Patients: The funding for clinical trials, particularly RAP-219, could lead to the development of new therapies, potentially benefiting future patients.
• Creditors: A stronger cash position resulting from the capital raise generally reduces credit risk for the company.

Next Steps

• Closing of the public offering on or about September 11, 2025.
• Deployment of net proceeds to fund ongoing and planned clinical trials for RAP-219.
• Further research and development activities.
• General corporate purposes and working capital management.
