- "You've mentioned that GARDASIL shipments to your partner in China have decreased and that inventory at Zhifei remains above historical levels ; what specific strategies are you implementing to address the demand challenges in China, and how confident are you in achieving your goal of over $11 billion in GARDASIL sales by 2030 ?"
- "Operating expenses have increased significantly due to strategic investments and charges related to acquisitions like EyeBio and Curon ; can you provide more detail on how these investments will contribute to your long-term growth and justify the increased expenditure ?"
- "Given the decline in GARDASIL sales in China and the anticipated similar level of shipments in the fourth quarter , how do you plan to mitigate the impact on your overall revenue growth and what other markets are you focusing on to offset this shortfall ?"
- "You have stated that your Phase III pipeline has nearly tripled over the past three years to more than 20 unique assets ; can you elaborate on the timing of these assets reaching the market and how they will contribute to revenue in the face of upcoming patent expirations, especially for KEYTRUDA ?"
- "In terms of capital allocation, you mentioned you have capacity to do 'pretty much anything of any size' but are focusing on deals in the $1 billion to $15 billion range ; with the increasing competition in the obesity market, why are you limiting your deal size, and how will this approach enable you to remain competitive in high-growth therapeutic areas ?"
