Management Comments

• We are a clinical-stage biopharmaceutical company dedicated to delivering on the promise of targeted protein degradation science to create a new generation of small-molecule medicines that transform patients lives.
• By leveraging our proprietary TORPEDO platform, we have the capability to efficiently design and optimize small molecule protein degraders that are highly active against their desired targets.
• Going forward, we will prioritize MM development for cemsidomide.
• While we will complete the ongoing Phase 1 trial, we have made the decision not to advance CFT1946 beyond the current Phase 1 trial.
• Data generated from the CFT8919 Phase 1 trial in Greater China will inform our ex-China clinical development strategy.

Industry Context

The biopharmaceutical industry is characterized by rapidly advancing technologies, intense competition, and a strong emphasis on proprietary products. Targeted protein degradation (TPD) is an emerging therapeutic modality attracting substantial interest, with numerous biotechnology and pharmaceutical companies developing degradation-based therapies. The company faces competition from both TPD developers and those using more traditional therapeutic modalities like small molecule inhibitors, antibody therapy, and gene therapy.

Comparison to Industry Standards

• The filing does not provide specific comparable company financial or clinical results to benchmark against industry standards.
• The company operates in a highly competitive landscape with many larger, more established pharmaceutical and biotechnology companies that possess significantly greater financial resources and expertise in R&D, manufacturing, and commercialization.
• The TPD modality is relatively new, and no regulatory authority has yet granted approval for any therapeutic of this nature, making direct comparisons to approved TPD products impossible.

Corporate Governance

Legal Proceedings

• Not currently party to any material legal proceedings.

Related Party Transactions

• Betta Pharma is considered a related party to the company due to Betta Investment (Hong Kong) Limited's purchase of 5,567,928 shares of the company's common stock for approximately $25.0 million in January 2024.

Stakeholder Impact

• **Shareholders**: Face increased net losses and potential future dilution from capital raises, but also benefit from progress in clinical programs and collaboration milestones. The increase in authorized shares provides flexibility for future capital raises but also carries dilution risk.
• **Employees**: Impacted by stock-based compensation, which decreased in G&A, and the 2024 restructuring plan that reduced the workforce by 30%.
• **Patients**: Potential for new therapeutic options, particularly in Multiple Myeloma with cemsidomide, and NSCLC with CFT8919, but also face uncertainties and risks inherent in early-stage drug development.
• **Collaboration Partners (Roche, Betta Pharma, Merck, MKDG)**: Continued engagement and milestone achievements indicate ongoing progress and value in partnerships, but the discontinuation of CFT1946 beyond Phase 1 highlights the inherent risks in drug development programs.
• **Creditors/Suppliers**: Subject to the company's financial health and ability to secure future funding, as well as broader economic conditions and supply chain stability.

Next Steps

• Continue ongoing first-in-human Phase 1/2 trials for product candidates.
• Initiate later-stage development and potential registrational trials for product candidates.
• Advance additional product candidates into preclinical and clinical development.
• Continue to invest in the proprietary TORPEDO platform.
• Seek marketing approvals for any product candidates that successfully complete clinical trials.
• Potentially establish a sales, marketing, and distribution infrastructure and scale up external manufacturing capabilities for commercialization.

Key Dates

Recommendation

The company reported increased net losses and a higher cash burn, alongside a strategic decision to discontinue further development of CFT1946 beyond Phase 1, which are negative indicators. However, the company maintains a solid cash position expected to last into mid-2027, and key collaboration programs (cemsidomide, CFT8919, MKDG, Roche) are progressing and achieving milestones. Given the early clinical stage of its pipeline and the inherent high risk and capital intensity of biopharmaceutical development, the current financial performance is concerning but not unexpected. The cash runway provides time for the lead programs to mature, but the long-term viability hinges on successful clinical outcomes and securing substantial future funding. A 'hold' recommendation reflects this mixed outlook, acknowledging the risks while recognizing the potential of its core TPD platform and ongoing collaborations.
