Management Comments

• Pete Smith: REM-422 has demonstrated favorable safety and tolerability data, with no dose-limiting toxicities observed to-date.

Industry Context

StockSavvy.ai notes that this merger follows a broader trend of struggling small-cap biotech firms utilizing reverse mergers to provide private, high-potential clinical-stage companies with immediate access to public capital markets and liquidity.

Comparison to Industry Standards

• The use of CVRs is a common mechanism in biotech M&A to bridge valuation gaps regarding legacy assets.
• The focus on RNA-targeted therapeutics places the company in a competitive landscape alongside firms like Ionis Pharmaceuticals and Alnylam Pharmaceuticals, though Remix's small-molecule approach to RNA modulation is distinct.
• The 43% overall response rate in ACC is highlighted as a significant clinical benchmark in a disease with historically limited systemic treatment options.

Corporate Governance

Stakeholder Impact

• Passage Bio shareholders face significant dilution but gain exposure to a new clinical pipeline.
• Remix shareholders gain access to public markets and additional capital.
• Patients with ACC and AML/HR-MDS may benefit from the continued development of REM-422.

Next Steps

• File registration statement on Form S-4 with the SEC.
• Obtain stockholder approval for the merger.
• Complete the concurrent private placement financing.
• Close the merger transaction in Q4 2026.
• Continue enrollment in the Phase 2 ARIA study for REM-422.

Key Dates

Recommendation

The merger provides a clear path forward for the combined entity with a funded runway, but the significant dilution for existing Passage Bio shareholders and the inherent risks of clinical-stage biotech development warrant a cautious hold until the merger closes and further clinical data is validated.
