Key Dates

Recommendation

The settlement with Alexion is a significant positive development, providing substantial cash and resolving a key dispute. However, the company continues to incur significant operating losses and its pipeline is still in clinical development. While the outlook is improved, the inherent risks of drug development and the long path to potential profitability warrant a 'hold' recommendation until further clinical and commercial milestones are achieved.
