4. Financial Performance:

- Collaborations: Revenues from collaborations rose significantly by 225% compared to the same period last year, bolstered by milestone payments and increased activities with partners like Roche and Regeneron.
- Costs and Expenses: The cost of goods sold remained consistent with 15% of net product revenues. Research and development (R&D) expenses increased due to ongoing clinical studies and preclinical activities. Selling, general, and administrative (SG&A) expenses rose as well, driven by enhanced marketing efforts for TTR therapies and strategic investments.

5. Future Financial Guidance:
- Alnylam reiterated its 2024 financial guidance, projecting combined net product revenues between $1,400 million and $1,500 million. Net revenues from collaborations and royalties are expected to range between $325 million and $425 million.
