Key Decisions for Investors

• Investors should view these strategic moves by Eli Lilly as reinforcing its long-term growth prospects by bolstering its pipeline in high-value areas like non-opioid pain management and RNA-based therapeutics.
• Consider that while the total deal values for both the SiteOne acquisition and Rznomics collaboration are substantial, a significant portion is tied to future regulatory and commercial milestones, which introduces a degree of uncertainty alongside the potential upside.
• Monitor upcoming clinical trial results for STC-004 and progress updates from the Rznomics collaboration, as these will be key catalysts influencing the realization of value from these investments and impacting LLY's future performance.
