Eisai Investment Narrative Recap

To own Eisai, I believe an investor needs conviction in the long-term potential of disease-modifying Alzheimer's therapies, especially Leqembi, and the company's ability to grow its neuroscience franchise while navigating fierce price and reimbursement pressure.

The recent FDA approval of Leqembi IQLIK for subcutaneous maintenance dosing in early Alzheimer's is a key development.
