AI Summary

3.0
Negative

OMER's thesis has shifted from a binary narsoplimab re-rating story to a much harder test of whether YARTEMLEA's early sales can build a real commercial base fast enough to offset the EMA setback, ongoing losses, and legal overhang—until quarterly revenue scales and the stock reclaims resistance, the risk/reward remains fragile.
